Pretty cool idea. It's a bit difficult.
It's really good that you show how to cast the spells.
An idea: Do you think you could have a really low damage fireball but that is really easy to perform (like pressing left and right). If you do so, I could use some when I panic because the enemies are pretty close.
Thanks for the feedback!
I plan to tune down the difficulty in the future. The shortest spell is Spark (right/left/right). The problem is that spell key combinations are not allowed to "overlap", so having a really short spell blocks alot of possible combinations. I probably redo the hotkeys eventually, maybe even let the player choose the combination themselves.
