Hi !
You made quite a complete game in such a short time, well done !
I like the multiple-puzzles system and using time and mistakes as a threat work well with the theme. I had fun until I died after 6 rounds x)
Just one thought: I'm autistic and all the loud, unpleasant noises when threat rises hurt my ears a lot (so now I'm crying, meh). I would have displayed a warning about this and added a box to toggle and deactivate annoying sounds for people they can annoy/hurt. But that's very specific to my disability so I understand people who don't share this sensibility don't think about it spontaneously ;)
