Failbrawler is fail
Boss / Thug enemies are pointlessly difficult to defeat. For a game based in creating combo strings, there are way to many enemies immune to combo stunlock-- this is especially annoying when they can break your animation frames with their unblockable attacks.
Abilities for your character are absurdly overcosted-- intentionally, I expect, so that buying the mochigames items seems appealing.
Art is good enough, I guess, if generically anime.
On top of that, another opportunity for Mochigames to pretend they have a business model. Screw off, flash games aren't worth money.
