Chill concept! Very reminiscent of early tamagotchis or digimon games.
Would love to have more bunnies at the same time, and a bit more UI bars for the bunny's status. Very well used and responsive buttons and SFX feedback. The resolution was not fully scaled but super minor thing, didn't affect gameplay. Music also randomly stopped for me as well. Clicking the bunny itself to take care of it might be a bit more intuitive. The waiting for evolve was a bit long but that might be from the lack of side activities.
There's a lot of potential with the bunbuns, especially if they evolve differently depending on certain factors.
Congrats on the first jam submission! Fun time!
