Fate...you are full of crap. Tried all 3 avatars. Upgraded Minotaurs like you said but level 4 only gives 132 gold..wtf. so can buy 5 of them. doesn't kill enough to buy more.
could you add a minor tutorial explaining the upgrade system. I looked at it and felt incredibly overwhelmed sense nothing explains perks of investing in each class/scroll things.
Glad to see that all the comments have thoroughly mad the dev mad. I do a lot of tower defense and ran across this one late. It's the hardest "normal" level I have ever played. I did skip the 'easy' one as seeing no point. The bugs are out of the game...well sorta. Apparently the marshmellow guys enjoy being shot b/c they don't slow done and barely die.
Thanks :)
