This is a nice idea. I liked the different abilities that you could use, and I can imagine a lot of ways this could grow in the future. It was a little confusing figuring out how to use them at first, but it was fun to play around with once I got used to it. I couldn't tell why you'd ever use the automatic attacks since you also take contact damage from the enemies - it seems like if you're trying to avoid damage to just use the skills, although getting fully healed on level up does mitigate the worry for that.
It's a shame that you couldn't get more of what you wanted in, but hopefully you have a good time in university!
