I do think it could help a bit more feedback and explanation. However, reversing the controls having a more puzzle/turn-based game fits the theme quite well, in addition to you not casting spells and rater changing the directionality of spells, but you should also indicate this in your description of "How does your game fit the theme?"

Very good game, it was very engaging and well thought out! It is a tiny bit confusing at the start as to what everything does, but after you (quickly) understand, it is really fun and exciting using the different powers in a new and unique way every level! Very great concept and execution, and I can easily see it becoming bigger and better if you ever decided to continue development!

Very cool game, great job on the art. The concept is very cool and was probably hard to implement, in unity.  Great job(:

Cool idea! I played all the way through. I've always loved games with fun spell interactions.

I think controls require some work, it's annoying that i have to click the mage to pick a spell, there's not enough feedback, no audio is really audible :v. Anyway, i don't think the game fits the theme super well, but it's a cool idea for a puzzle game with a potential. I'd play a polished version of this.
