How many languages does the game currently support?
Currently only english, A translator is currently translating it to chinese.
I've been waiting for this game and I can't play it on Android 🫠
Thanks for your patience! We'll update as soon as possible!
Can this game be played on Android?
Hello we're working on it might release with the second update.
Is there chinese translation in Discord?
I think there's people trying to translate it there brother.
Hello developer, can you add Vietnamese to the game? If so, thank you.
Hello, can do but i dont have anyone to translate.
where are you from?
Quick question whats the "interactive elements" supposed to be?
Hello, are you referring to the quest? That's actually a bug we discovered after releasing the game. It should be fixed on the next patch.
Hello, can I add the Android version?🌹🌹
Hello What do you mean?
I'm playing in windows and for some reason the Ui to change rooms and view your stats with Rika keeps dissappearing. Is there a way I can fix this?
Hello! Do you have logs? feel free to send it over via discord so we can check. Also can we ask if you used URM?
这部游戏的剧情很好，建模质量也很高，角色对话很让我喜欢，如果可以，我希望见到更多的与她亲密场景，更多的性爱场景，建议开发一下肛交
I've played through the story so far and I've certainly enjoyed it. Though, there are a couple of points which don't really make sense to me or which could be improved on.
Off the top of my head, those are (slight spoiler alert):
- When you meet Rika, she tells you about 3 other houses, which still function, mentioning how she will talk to you about them more the next day. However, they aren't even mentioned again, before you fully gain her trust, which storywise probably takes a couple days/weeks. Which is... kinda bad in itself, given Rika's urgency for her own mission.
- After Rika goes to bed the first day, we 'check' on her (Our character is a creep - at least he seems to be aware of that). Unknown to our character, she is awake. And yet, this doesn't come up again, like at all. We simply gain her trust by spending time with her, even though she should kinda mistrust us due to this point alone.
- There doesn't seem to be a way to tell the time of day. There seems to be 3 or 4 times each day (can't remember right now, probably something like morning, noon, afternoon and evening). Would be nice, if some way to tell the time would be added, though I guess it's not absolutely nessecary. More of a personal preference, really.
- Some scenes were shown as completet as soon as I reached th requirements, but I hadn't seen them yet. They played at a later time.
- After some scenes with Rika, I couldn't change the location. I had to perform a random action in the location I was in to 'unlock' the other locations again. I assume this is a bug, though I'm not entirely sure about this.
- There was this optional mission, I believe it was called "Explore Boundaries". Does it do anything? Do I need to do that stuff to unlock everything and to "corrupt" Rika? Because... the way the player character acts is certainly disgusting and I would rather not do it.
- As someone else already mentioned, the "Home Explorer" mission seems to be bugged.
- After playing through the story and continuing in sandbox mode, I went on a supply run. Afterwards I had the Gatcha option, which wasn't really explained. The cards don't really do anything, as of now, right? I couldn't really see anything about them. After pulling the Gatcha and clicking on resupply, I had a blackscreen, with sounds as if another Gatcha was opened. Seems like a gug to me as well.
This was everything I can think of, off the top of my head. More than I than I originally thought there would be. Like I said, I really enjoyed playing your game and I will continue doing so, once you release an update. I hope you see this as the constructive criticism it is meant to be. You don't really need to change anything, after all the game is good as it is and maybe every point I've raised is intentional (apart from the mission bug at the very least). I couldn't possibly know.
Please continue doing the good work!
Hello!
Thank you so much for taking the time to write all of this. I really appreciate it, no worries, I always welcome feedback like this! It honestly helps me improve the game a lot, especially since I’m still learning both the development and rendering side at the same time.
Let me go through your points one by one:
The 3 houses Rika mentions
You’re right, this was supposed to lead into an actual scene where Rika asks you where to go next. That scene did exist… but I accidentally deleted it during development (rookie mistake 😅). Definitely planning to restore that because it makes way more sense storywise. Thanks for catching this!
Checking on Rika at night
Yep, that one is intentional. The “awake but pretending to sleep” part will tie into Chapter 1, so it’s not forgotten. Or why she was non-chalant about it.
No way to tell the time of day
That’s actually a UI bug. On the top-left (beside Tuesday | Room Name | …) there should be icons for time of day, but I forgot to swap the placeholder text out. Good reminder for me haha.
Scenes marked complete before watching them
I’ll look into this more closely. Could be a timing/flag issue, thanks for letting me know!
Getting stuck in locations after some Rika scenes
Yes, that’s a bug I’ve been debugging as well. You nailed it.
“Explore Boundaries” mission
This is 100% optional. You don’t need to do it to unlock anything or “corrupt” Rika. Corruption has its own system (which I also forgot to link properly to the companion stats 😅). So feel free to skip without missing content.
“Home Explorer” bug
Confirmed. Already fixed via hotfix, but since it wasn’t game-breaking I held back on pushing updates until more content is ready.
Supply run & Gacha
Correct, after the prologue, supply runs are purely optional. The gacha system itself is still being implemented, so right now it doesn’t affect anything major. In the upcoming mini update, you’ll have the proper gacha screen and rewards. As for the black screen after resupply: could you tell me which device you’re using? That’ll help me replicate and squash it.
Additionally there was also a duplication bug regarding the supply run. So i'm pretty sure you'll experience this aswell. But this has already been fixed.
Once again, thank you for such a thoughtful write-up. I’m really glad you enjoyed the game so far, and feedback like this makes it so much easier for me to refine everything. More updates (and fixes) are on the way, I’ll keep everyone posted via Discord/devlogs.Glad I could be of help!
Yeah, I forgot about the little boxes next to the day and room name, should have suspected that to be meant as a way to tell the time.
The scenes that are marked as completed before watching them are only the ones that trigger automatically. Since they still trigger anyway it isn't really a gamebreaking bug, just harder to track which scenes have already been seen.
Glad I don't have to do the "Explore Boundaries" mission to see everything. At least the narrator (you :p) agrees with me on these scenes.
Regarding the Supply run & Gacha, I'm playing on PC. I don't know, if I'm even supposed to be able to click on resupply. When I close the Gacha screen without clicking on it, I can't reopen it. Which might be another bug, I honestly am not sure if I have more than 1 supply or not.
hoehoehoe degenerates.. Man I love the idea .. will try it out and see... kira ora fwens
Thank you very much!
Will there be an Android version later?
Hello, yes we will release the android version soon!
Oh. I'm really looking forward to it. Will there be versions in other languages?
Yes we are aiming to translate it to other languages aswell!
That's really great (๑˃̵ᴗ˂̵)👍
Will have Chinese？
Oh when will it released to android?
We are aiming for this month!
I'm really eager to play you're game! We're waiting..
hey im trying to download the game but it keeps giving me another zip file, can you tell me how i can fix this.
Hello, can you re-extract the extracted zip? Sometimes, gdrive or Mega Link can re-zip the file.
Really interesting so far, just a couple questions. I finished the story so far, but I still have the home explorer mission. Can't figure out how to do it. I also haven't seen the lower 2 of the preview images, are these part of the home explorer mission, did I miss them, or are they not in this version?
Hello, thank you very much for playing the game. Home explorer is a bug which will be fixed in the hotfix, same with the recon mission.
FINALLY !!!!!!!
Thank you very much for the support!
I see the potential fam, so godspeed to you and I hope you don't abandon your masterpiece of a game is all I'm asking :D
Really appreciate the support and joining in early! Appreciate you believing in the project. Don’t worry, I’m not going anywhere, we’re gonna see this through to the end
Woooooo. Yeah baby, that's what we have been waiting for!
Thank you very much! really appreciate the support!
Woah awesome! I can't wait to play it! Also congratulations on release! I wish you guys the best with Deep Freeze Protocol!
Thank you very much Lolling!
