I tried out your game, didn't get far in. I encountered a fair amount of glitches during the time I did play, here are my suggestions and some glitches I found:
Glitches:
1. You can cling to the wall and climb it by clinging on itand spamming space. Not sure if that was intentional or not.
2.While in the "Hub level" (I'm not sure what its called)
if you jump high enough and hit the ground you can clip through it, this happened to me the first time I launched the game, I got stuck in the ground.
Suggestions:
1. Fix the controls they are god awful.
2. The textboxes are hard to read because of the neon font mixed with the screen blur.
3.Reduce the size of the textboxes, they take up alot of space.
