This is winner material. Really good and polished game! Really hard too, the second boss whoops my butt pretty thoroughly.
On the second stage some enemies aren't loading though. I get a "warning" but no enemy spawns. Also special rooms could be more exciting - getting 5g chest or a shrine/well when you need neither is disappointing.
Honestly, this could be a really fun roguelike once it's all fleshed out. Graphics, SFX and everything is awesome!
