One of the few games I actually finished in this gamejam :]! Really like the music you use for the whole thing, the mechanic is simple to understand but still challenging to do well, the level design really worked well throughout the whole process! :D
No checkpoints at first did concern me a bit since I've done a similar type of game before called "Forgotten Soulsword" but I realized even your "danger" areas are designed in such a way that you can't really fall down them unless you're REALLY trying to xD!
Awesome work amigo, really neat submission! x]
