I like the idea and the gameplay. The abilities are fun to connect. Kinda gives the LoL vibes from it. Not bad inded. The girl (model) is cute abeit devoid of animation. My problem is that I got to wave 15 or so then I pressed esc to pause and it didn't. Well, it is fine though. Just played it again.

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!

another one that seems like a good first unity project... the facing of the girl should maybe be controlled by the mouse position... the wave counter gets sort of broken for me around 6th wave... 

Sounds / music would be nice to add... something that tells you visually you are getting hurt.

Unfortunately the game hasn't started on Win10. "Fatal Error. Failed to load mono"
 

It feels like a good prototype for a game pitch. 

The verity of magical abilities is great and the pathing for the enemies works perfectly. 
I really like the character model too, it would be cool to see this one grow with some rigging and enemy designs.
