Really, really, good. Feels like single-player fantasy Into the Breach - positioning is critical, and so many abilities push and pull enemies. I'm just getting started with LÖVE, but it looks really promising so far.
Two things:
You can die if you run out of health when you reach the exit. I was poisoned, and died instead of going to the next level. I think this actually makes for a great moment in the early- or mid-game, but I can imagine it being pretty rage inducing on floor 23.
Also, combining the Feral Gauntlets and the Monk's Amulet leads to uncontrollable behaviour. The diagram on the left is what I would expect, the diagram on the right is what I got (red: attack, blue: attack + move).
I might have the exact positioning wrong but you get the gist.
