Great art, good concept, interesting gameplay. It's got a good base and is overall a good game.
Only complaints are that the laser beam attack lingers too long, and the difficulty is too low, but these have already been brought to light. Having all spells from the get-go and losing them on progression is unique in a good way, but it would be better if there was something else to obtain in place(like a passive), although it works fine even without.
Good job on the game.
