Loved it! The game was fun to play! I finished it, although had to do it 2 times.
The backing track is awesome! I love how good the disturbing soundtrack makes me unsettled! I don't know if you guys made it from scratch but the dissonance and out of pitch moments in the soundtrack makes it so unsettling!
The puzzle design is also well done! The necessary items to escape are well hidden but not entirely impossible to get. Additionally, the help button really is a good addition especially to those having trouble in some parts of the game.
For my only criticism, the design. I think you guys should have put more time on in-game design because it breaks the surrealism of the game when the elevator looks plain and a solid color, although btw your cover art is really good and your game page is really well made.
Overall, congrats on making a game! This was a 3 day gamejam and a 3D game that's playable and this finished is already an accomplishment by itself. Well done!
