Amazing game! This was fun to play, managing resources and spawning a whole horde of zombies wwww I only couldn't figure out how to upgrade (was trying to unlock fireball)? Not sure if there was a cost of souls I wasn't hitting or something I had to do other than click on the upgrade I wanted hmmm. Even so, since this is a prototype, I really look forward to the full game! Would come back to play again ദ്ദി ˉ͈̀꒳ˉ͈́ )✧
