Cool concept, but I think my game glitched out and I lost at 93m, despite my army of dragons and mega-mages.. :(
Not sure what happened, but it just kicked me out to the score screen randomly.
Fun concept once you figure out the way to combine! I was confused for a while when I couldn't figure out the mutate button. The tutorial helped but I tend to go straight into the game and try figuring it out intuitively first. I like the music and graphics a lot! The dragon mutation seemed overpowered, like it was just melting everything and I had 3 of em. Super satisfying though. My first run I did without any mutations and it was a lot harder so getting the dragon on my second attempt felt awesome. It would be cool if you could keep mutating them once they're in play and get even stronger units!
