I really want to give this game a fair shot because I can see that it may be a pretty interesting game. However there are too many problems with it, as a platformer, for me to continue. Since this is your first game, I'll give you some pointers should you want to make more.
-The controls are much too floaty. You stay in the air much too long, the gravity doesnt feel realistic. The left and right movement accelerates too slow and decellerates too slow, so it feels very very slippery. You should hit full speed and come to a complete stop either very quickly or immediately.
- The hitboxes for the enemies was much too large. Generally as a game design rule, you want positive objects to have a larger hitbox than their size and negative objects to have a smaller hitbox than their size.
The sad thing is that these were really the only problems that I came across, but it was enough to make me not play the game. Good luck with your future projects!
