Nice work.
Especially since this I think this is your first jam.
The graphics are cute. I love the little hat bounce animation. And the music choice is perfect.
I like the randomization of the “little rocks” but I think a little more variation in obstacles would have added a lot of replays replayability. Even if the mechanic was the same, just making the art a cactus, or a fence, or something.
Nice little game though. Good luck with the jam!
