Love the overall presentation with the drawn/painted art-style and the cute blob. I liked the music change when the mode changes. I think i need a mouse to play this... I played with a trackpad, got pretty far. The aiming felt slightly wonky but i feel like it would work decently well with a controller. I feel like the difficulty is not bad, although there might be a slight clash between the cutesy aesthetic and the difficulty, I think you mentioned something about adding a normal/story mode to just chill the game. That would be a neat addition.
Great job otherwise!
