Made it to wave 31 before getting too bored to continue
Tack Shooter spam is overpowered (in case you don't get that reference I mean Fireball Launcer) but in the later stages some horizontal protectors helped keep me safe as well.
I loved the very unique take on the tower defense genre. 5 stars on innovation. The graphics were cool and the song was decent as well. One minor problem with that:
In fullscreen view (which was default by the way) you could see outside the map because the game didn't scale with the window. Unsure how intentional that is...The game fits the theme better than most. There was one minor problem I had with the game design, that being that the game is not super balanced. If I could add one thing it would be more progression: pebbles that have more hp start to replace snow and towers get some upgrades to increase possible strategies.
A very good creation, I like it!
