Very nice art! The spell cast system is interesting (especially the fireball). It is too bad the controls feel a bit "clunky", it was a bit tedious to cast the spells. No health bar did not help for feedback, but for the jam it is quite nice !! :D
I could not play in fullscreen too but I don't know if it was just a problem on my end so I did not take that into account in my rating. :)
