I found it a nice twist, there are not many games like this. But it would be very nice to have more than 1 song (with the same bpm), it gets pretty boring after some time.
This game has great potencial!
I liked the gameplay, the llama in-game and the cheerleaders. It's nice how they help you during wave battles, but have no use on bosses and tavern fights. It makes you think a lot to balance that in the beginning, when you're short on cash.
However, the animations are way to slow, and it's kinda unballanced. The third boss (undead) is waaay too strong, I had to upgrade 2 levels on the graveyard to beat it, and then the fourth city became very easy (I played on normal difficulty).
Anyway, good game!
I don't know if this is cheating, but there's a program named "Fast Mouse Clicker" where you can set your mouse to click 9999 time/s. It didn't take the fun out of the game. At least for me.
Thanks for enjoying the game and for the genuine feedback :D
