Definitely an interesting twist of the classic Roguelike formula, in a very well made pixelart style! The music is super immersive even if it's a single track thanks to subtle but incisive changes to the arrangement to highlight different, specific moments of the game (menu, gameplay, boss battle).
Animations, VFX and SFX are very satisfying to watch/listen to.
Only downside is the low number of different enemies which makes the game feel a bit repetitive once you've dropped 18-20 perks.
10/7 would playtest again.
