Surprisingly addictive although I ran into performance issues when I got to a large scale (when my mana bar was at around 2000) - snowmen kept spawning in groups of 30 which caused my computer to freeze and I had to close the game. other than that had a good time. graphics are ok but could use some polish and styling. I liked that it's an original take on the old tower defense genre.

I think the problem was lack of pooling or prewarmed pools if you were using pooling
When you instantiate many gameobjects in a single line during runtime it often causes freezes and this issue is resolved by either using prewarmed pools or dividing the instantiation into several frames, thus avoiding writing too much to memory in one line.
