Yo.
Nice Gamplay.
I think you should make the camera follow the hero. The game system makes you want to discover more with more spells and possibilities.
However I find it very incomplete to be put in the Jam. Just a small level with a small story could have done the trick but without that it is not in the theme of the Jam. Too bad because frankly I find the gameplay very correct and all your mechanics seem to work. I wish you do not get discouraged.
I send you power and say you good work!
