Sprite work is great! Music also vibes with the cartoon-ish feel of the game.
I think the core combat loop could be improved by making the "Fight"/"Skill"/"Item" abilities auto-pick on the same loop as the enemy. Then the player wouldn't need to spam the mouse for their desired outcome.
I would also love something else for the player to do, or ways to mix up which dice the "Spell" proc'd on. I saw it does 15 damage on a 1/6 hit, so that goes to an average slightly worse than raw-rolling the D6 (average 2.5 vs 3.5).
The core game was enjoyable, good work!
