I'm surprised more people having tried/rated this game. This feels like one of the more complete packages in this game jam, and all from a solo dev no less! Very impressive.
The voxel art style is neat and consistent, harmonised by a moody, sepia colour theme that gives me fantasy RPG vibes. I like the added detail of your character aging or changing appearance when it wins a round. The UI design is simple but efficient and matches the overall theme. The rock/paper/scissors gameplay was easy to grasp, though relying on random guesses to win doesn't feel as satisfying. But I did keep playing to see how much the character would change each round. Sound is good.
Great work!
