I read in the description that this is your first game for a jam. That's amazing! It's way better than the first game I made for a jam. I encountered some minor bugs, like one time I fell into a pit and didn’t get a game over. But those are things that can be fixed in the future.
The music is very pleasant, and I liked the character sprites. Welcome to the wonderful world of Jams; I hope you participate in many more!
