Quite a cool and fun build-based game, I see a lot of potential in this one, could become the next popular Slay the Spire-like game with the right balancing and enemies.
I found the lack of enemies beyond the skeleton to be somewhat confusing, but after reading the comments I can understand why they cut the others due to time constraints, although the audio could be a bit louder (I didn't know that the game even had sound effects until I turned the volume up to 100 on my laptop).
Besides that, this game's really fun even in it's current state and I wish it receives further support and development. I wouldn't mind if I got addicted to a gameplay loop like this one.
