This game suffers from an inverted difficulty curve, in that it gets easier as it goes on. I was able to unlock all 9 abilities and I think the bomb and snowball where the best over all. The lightning one had a really cool effect though. Nice work!
Well the zombies also get stronger (faster and do more damage), but I agree that it gets easier as you unlock more spells. I should have made them get stronger faster but I didn’t have enough time to balance everything ^^’
The lightning is one of my favorites, thank you :D
