Nice game with cool game mechanics!
But yeah, it took me a bit of a time to figure out what was going on.
- At first I didn't understand who I was playing for. You should mention this in the rules and show it visually with a wizard sprite.
- Also, at first I didn't get the moving dungeon mechanic. It was mentioned in the rules, but it would be nice to show it visually as well. Like, add 2 images of the dungeon field before and after the dungeon moved up.
- The game is missing a few animations like explosions, death, damage. I'd like to see the standard HP number deduction animation. Highlight the wizard's HP with some animation when hit. You can also flash the screen red.
