Lovely game!
Art is super cute, the enemy design was pretty creative!
I did like the audio, when it comes to spell noises and stuff, I did miss a lot of it, mostly a small musical theme and some game sounds that were not present.
Control wise, it was good, but a bit annoying that the attacks were not all the same, I mean I can understand why the lightning would be different, but I think that they should have all use the same mechanic, even if you have to make two attack moves, one direct from staff taking X mana and another on the mouse pointer taking Y mana, and balance it out, but nothing too much.
Regarding fun, gave 5 stars, I think its just very balanced difficulty wise, and the fast pace makes it fun, would like to see a finished game outta of it :)
I mean no harm with the feedback, all constructive, mostly since I came to the page from your discord pos so I know you had some setbacks, so congrats!
