Cool game, I love rougelites. Only suggestions I have is:
Enemy location indicator: Although the maps aren't that big, I think an enemy location is a nice QOL think to have especially since (at least to my knowledge) you cannot zoom out to being able to monitor the entire map. It'll help you out with keeping track of where enemies, especially if they use ranged attacks outside of where you can see.
Improved hit registration: I play on MnK. I know that your attack direction is dependent on where your mouse is positioned. I can't accurately describe it but sometimes it feels like there's an interaction between directional inputs and where my mouse is pointing which results in an attack not landing. If you're playing normal it probably doesn't mean as much. If you're playing on No Insurance, it means a little more because your attacks flinch small enemies. If your hit doesn't register, you're gg'd.
