I like the idea of the sunrise api and that you can only play the game when the sun is up. It's a nice implementation of it being not in your control, but in control of your environment. Also the walls seem procedurally generated which looks nice. I would have made it a bit more difficult though, there are many segments where I could go straight for a long time without any issues. but that is all fine tuning, for which there is never enough time during a jam. Some collectibles on the way could also be a cute addition for the future, collectibles that grow a flower, or boost your speed for example. Overall, nicely done!
