Seems incomplete, but the story setting looks interesting. I kept getting stuck whenever I clicked the item disk.

It looks interesting and atmospheric. Although a bit confusing in places, you quickly get immersed in the game.

@roccay @lehanfox @nadia-pixel Thanks for playing!

We’ve taken some time to polish and complete the parts we couldn’t finish during the jam, and have updated the game as an Extra Entry. You can now experience the full game in the HTML version.

If you’re interested, we’d really appreciate it if you could give it a try and share your feedback!

Nice atmosphere! The limited palette made it a bit hard to see what was going on sometimes, but I enjoyed the experience. Things were put together well, and the plot twist(?) when you disable the security system and open the door got me interested enough to finish the playthrough... but I failed the mission because I couldn't figure out how to refill the cryo chambers :(

@ale Thank you for playing and feedback! To refill the cryo chambers, you need to get the coolant from the coolant storage and use it on any terminal before the chambers.

Really liked the style and presentation it looks amazing! I find the pixelated dithered look and the palette to be a fantastic choice that complements the sci-fi horror tone tone very well!

I thought the puzzle elements were the right amount of difficulty, there wasn't really a moment where I felt lost, everything was communicated well/was intuitively designed.

The writing is good too! the story had me intrigued enough to finish every step I had to do for a good ending.

I don't like it when a game doesn't tell me what it wants from me; this is one of those times. The goal and the motivation to achieve it are the most important aspect of a game.

Great work! I truly felt like Sherlock Holmes while playing this. The gameplay mechanics are incredibly engaging and make every discovery feel rewarding. The atmosphere of investigating a biological threat is spot on and kept me hooked the entire time. It’s a very polished experience for a game jam entry!

Ohhh, this game is awesome!
(The sound and visual feedback when hovering over items is super satisfying!)
(And the puzzles next to the computer — they’re really fun and beautifully designed! The ribbon-like scrolling lines look so cool!)

I like the style and visual effects of this. It feels very refreshing. The setting of the story is also quite interesting. However, I think the difficulty of the game is a bit too high. But it's really great that it was completed in such a short time!

The art is great and the dithering really did a lot of work for the atmosphere. That and the UX really sold me. The beeps and boops of mousing over everything was satisfying and the eerie story was well done. I liked the multiple endings, and the slow reveal through the computer.
