This game is incredible, I love that changing sizes isn't just a limiter to force you to defeat specific enemies, each size also has its own attacks and upgrades. The simple graphic is perfect, and the sounds are very nice, even if a little repetitive.
I wish the game were infinite, even if there's only one boss, you could make it so that the enemies get more health after you defeat the boss, and continue after that. And another thing is that the small sized character felt very weak compared to the others, sure, it shoots faster, but the dash was too short and the cooldown was too long for it to be worth more than the others, which have huge knockbacks.
