I like the concept of a 'die as fast as possible' game, but this game wasn't really a puzzle or speedrun game, more like a tedious collectathon. I would recommend not making the moving speed slower in a speedrunning game, just because it sort of eliminates the whole purpose.
the UI was great, however, and it helped a lot that you could lower the video settings, but only because it was very poorly optimized.
The art assets were great! I wholly thought they were pre-made!
Also, maybe a bit weird to let the paraplegic child be able to jump.
