Overall i love this type of game, it reminds me of binding of Isaac, the overall art was really cohesive and although not visually amazing, it really did set the tone and vibe which is infinitely more important than a few good pieces of art in a game. The sounds also matched really well with the art, really cementing the theme of your game.
Some small gameplay feedback./
-as of right now the player is the whole collider, when navigating through the barricades and walls i often found myself having trouble fitting into tight spaces. a way to fix this is make the movement collider at the base of the feet, and the hit box for taking damage take up the whole player.
-taking damage didnt have enough impact, somtimes i didnt know when i was hit.
-chest sytem, at first i had a tad bit of trouble figuring out how to open the chest, a better indicator may help!
Overall good game just needs a tad more polish!
