Nice game. Maybe a little bit slow especially when you are outside of battle.
I played only the first levels and I would like to ask you, do later levels share the same layout? In lower levels it's basically square rooms with single hallways: no mazes, no inner obstacles or traps, etc. Is it so only because the first levels are supposed to be introductory ones? Or is it so also in later levels? Because as for the first levels, the environment does not pose any puzzle or challenge (traps? obstacles that force clever positioning?), so the game gets repetitive.
Please take these as constructive criticism! This is of course a 7drl so the game is expected to be minimalistic. But the basic idea is nice! :)
