Pretty hard, but i like the evade and get your boosts gameplay. here some feedbacks
* Make the character in different colors so it can detach from the bg
* Make some invulnerability frames after getting hit (on wave 2 if you get caught in the big eye attack, it's mandatory death)
* Delay the small eye attack after spawning so the player has time to evade it
* Update the level design so i can go up on the left side of the arena, going bottom left gets you stuck
