cool game and implementation, i suggest you tweak balance as now it's a very little room for player to learn the game (i mean dying 7 time just to understand game is not fun) you push player too early to be careful. and throwing new and more enemies also to soon. make this experience a bit longer and lighter at least at the start and will feel much better. overall great game feel, i like your game!
Hope you will try and rate my game also<3
