Good job! I recorded my playthrough - not sure how useful this is without commentary but perhaps it will help.
I should mention that I didn't really understand what the two types of pickups are, or how the percentage one works. But you're off to a good start, and I like the textures. Not sure if this is 1MA but the music is pretty decent too.
Also, please add controller rebindings! I was playing on a Dualshock 2, and the pause menu got default mapped to R1.
