I don't know whenever it's intentional or not but... stun and sleep can paralyze bosses so... it kind of makes the last fights easy compared to the cameras beforehand (and I don't remember if you can do the same thing in F*ckboys). I know that you don't unlock the skills right away and need level 15 to get them but to be honest you'll easily get these before final fights.
Other than that it's a fun recreation of F*ckboys! But I am curious what poster didn't make it into the game and why...
