Nice game. I think the artwork is really well done and I like the music choices. I like that the foreground elements were made transparent as to not obscure the player character too much. I liked using the mouse wheel to quickly cycle through different weapons on the fly.
I did find the combat too slow and sluggish due to the high cooldown of your different abilities. Having an ability or two with shorter cooldown would definitely help make the combat more fluid. I was also unclear of what the little pill-like things I was collecting were doing until an upgrade screen popped up.
Also, I encountered a bug when I dashed against a wall on the right side of the map and got stuck until all the enemies killed me, lol.
Nice job on this submission!
