This is a very nice defence game which I haven't seen yet in the jam! I had quite some fun with it, and managed to get a small highscore of 37 points, probably not too good but I'll take it. The turn-based mechanics are very nicely designed, and the graphics are very cute too. I especially like how each spell works differently with stuff like push-back, penetrating, etc. I would wish there existed some kind of damage over time spell as well, but hey it's already quite a lot with what we've got now. Well done!
I'd say the enemies spawned in very quickly, especially when you get over 20 points, which basically means you're never going to use spells that are not 1 mana, and that's a shame given that there is this system allowing you to choose the next spell. It's also a shame this game lacks a landing page, but I mean time is never enough in a jam so this is understandable.
Anyway, this is very well done! You should be proud of yourselves!
