Trash first game- Cube shooter

Hello, this is my first time creating a game so don'f flame LOL.

How to play:W and S to move up and down, dodge everything on screen + every time u reach a check point (100,150,200,250,etc) then the game will get harder + u will get mega charge where u can press space to fire and the bullet will go thru up to 10 enemies before disappear

What could be added: power ups+ more modes

p/s this game is currently very cursory and  I only make it in 2 hours
