Great stuff. For Slay the Spire fans, it's almost like just a constant balancing of relics.
Points of improvement for the full release:
- It could use way more sound effects (like when you press buttons or roll the slots)
- It could probably be more/fully keyboard-operated for the most part, other than item removals
- The music could be more complex (I don't know if you're seeking composers, but I'd be interested if so!)
