I enjoyed playing this despite some of the technical frustrations I'm sure you're already aware of. I did get stuck though, at the part where you have to go back left and down--couldn't seem to avoid the thorns below, not sure whether to go left or right.
Overall I think the concept is great and I can't wait to see what this game can be once you put some polish on it. For a 48-hour jam it's very impressive! Nice work!
