oof, that was a tough one to play... my fingers couldn't handle playing that for long.
The players movement is very limited and there were often times an enemy would spawn to my right and two next to each other on my left so even dashing couldn't get me to safety. I'd definitely consider giving the player a bit more movement or a simpler control scheme.
The environment and player art was great, the enemies not so much :P
All the game needs is some nice enemy sprites and a control scheme that are more accessible.
