Ayy an Isaac-like! I love the visuals, the hand drawn style is really nice to look at. Gameplay-wise, the game is a bit too difficult, in the way that the player's hitbox is way larger than it needs to be, making some rooms have unavoidable damage. What makes it an issue is that the upgrades have downsides that don't feel worth it, and the player usually comes out as equal or weaker than the next room. At the same time, the enemy designs are really cool and fun to dodge! Overall, I'd say the game just needs a bit of balancing and some more unique upgrades. Good job!
