40 waves of pure crap. Adding medals for this game was pure douchery.
No damage upgrade. Shitty spells. Shitty cooldown.
Too hard. It's baffling that this game has good ratings, but it's even more baffling
why have you decided to add medals to so many old and cringe-bad games of yours.
Edit: nothing says better how shitty this game is, when you get to wave 37 that lags enormously, because shitload of villains. You die, and they completely wreck your castle, and then there is "game over, start again". I wish I could give a -1 rating.
