I think it would be better to introduce the spells one at a time, it was hard to remember what they all did.
Was there no enemy AI? I didn't seem to get attacked at all. I mostly used the long-range spell as the others were very short range and targeting was difficult, I'm not sure what the difference was between them.
You got a lot done in the time so you should be proud of your efforts, just need to work on the new player experience
