Great 1-dev entry.
Here's some constructive feedback (as the one I'd like to receive myself). Bear in mind that these are totally expected for a gamejam and even more so with the shortcomings of being a 1 man team.
-Audio levels: Music is really quiet. SFX goes up to 0dBFS (clipping). I turned the volume up to listen to the music and as soon as I lost the sfx woke up the person in 1 room away.
-The tower-rotation effect would benefit from 2D cylinder warp effect (time consuming. totally understandable it wasn't a priority).
-It could be smoother for the gameplay if losing wont send you back to the title screen. Also reducing the 3,2,1, timer would make insta-retrying multiple times smoother and encourage replayability.
Cheers!
