Very cool entry, good job!
I think your gameplay loop is engaging, the movement itself is satisfying and has enough depth that you can always do things differently and save time by doing trickier jumps. Some stuff didn't feel too intuitive to me, like how bumping your head on a ceiling will kill your momentum and trajectory almost instantly. Also, it felt like doing a more horizontal jump took me way less far than it should, as if my character became a lot heavier when choosing that angle. I don't know, that part felt kind of unnatural to me, maybe you intended the jump to be that way but I think it could be good to take a look at it. I didn't get all the way through the game - I got a bit frustrated, which I think is kind of the point of your game, since it feels like sort of a rage game with all the setbacks to your progress and stuff. I don't think that's a negative, it's just that I don't think I'm the right audience in a way.
I think your use of the theme was very original and the whole concept ties in together very nicely. The game feels well thought out concept wise, which I like.
In terms of aesthetics, I think the art gets the job done pretty well. The rooms look complete since they're not just empty, which is a nice touch.
The music is alright, feels appropriately tech-y for the concept you've chosen. I think there could be a bit more sound effects, though, since I sometimes felt like the soundscape was a bit empty. That's just my two cents!
Overall, great entry, keep up the good work!
