Nice job!
I wasn't expecting the game to have so many enemy types. Every time I thought to myself "okay that's it" a new enemy type would appear like "no it's not, keep shooting my guy".
I think I valued getting player speed at the begining of the game since some enemies are faster then you but overtime DPS becomes way more important since enemies don't speed up (at least I think so - maybe they do) and the damage is also your source of healing while also defining your "progression speed". I think it would be cool to let player choose what type of powerup he wants when picking up cheese (just like in the mentioned below vampire survivors).
Also the fish animations are so stylish I am curios how did you make them?
Overall great game!
