That was cool! The art is charming, and the mechanics are fun. I especially like the combination target gallery and shmup avoidance gameplay; it's very satisfying to do well!
I might have just gotten really lucky, but the final boss felt much easier than the regular enemies. Regular encounters have haphazard movement patterns that can be absurdly difficult to react to at times, especially the floating skull that shoots fireballs.
The soundtrack is awesome! That said, the audio balance is a bit off in places. The regular dungeon music is quite soft compared to the rest of the game. Also, the sound that plays when you choose a curse is really loud; it peaked the audio to +3.5 dB!
All-in-all, great work!
