You can also buy the second most damaging weapon for coins in act I, the dagger.

Though the new update (new update again, I know) made every boss harder, except Lynx and Shogun. I beat the iOS version, and I'm waiting for titan. Back in the old versions of the game, bosses were just regular enemies that you needed to win three rounds against, instead of two; and maybe with a special perk. But now the new update turned bosses into ridiculously advanced enemies with super powerful moves.
