I like the art, I feel like the artstyle works really well for this game. Cozy vibes on point. And a touch of personality is always good. The foundation feels solid. The scope was managed well for the game jam.
From my experience with idle games: I think feedback / "feel" / "juice" is very important for idle games. It helps if the main mechanic feels satisfying to do. Also, small rewards that happen often or small goals to complete for that dopamine rush early on could be nice to hook players. Idle gamers also like collections and achievement hunting. It helps to make players feel invested.
I had fun playing:) Thanks for the game!
