I got to level 5 or 6 when my run was ended by phasing through a wall and falling into the void. Tons of fun though. The spells looked really cool and were interesting to use. It is a bit easy to cheese things by moving back and forth until your spell recovers, but that would be easy to fix with an enemy that is ranged or if enemies start to regenerate after not being hit a certain number of turns in a row.
The opening cutscene was super neat and I loved the premise. The whole vibe was great. I liked the background looking like a pixelated Balatro style thing haha. Gave a very ethereal feeling to everything.
