It has potential somehow. Unfortunately I believe I defeated the end boss, while not even having half of the spells. Also assigning the rules to the spell slots was more like trial and error for me. Maybe I am not smart enough for the logic behind it (or lack of english?). :D

Controls are clumsy sometimes, but you can get used to it in the end! 

After finishing the boss and watching the credits roll, the last level started again with a timer and I had to collect things. After that the level restartet without me being in the center of the screen and I somehow could not make anything. Not sure if this is intended after all.

But in the end: for a free game I really had some enjoyable time with it. So thanks! (=
