Mighty Morphin Power Rangers the Movie on Genesis. Overall, a pretty solid beat-em-up, if a little easy (it was for kids, anyway). Anyway, at the end of level 5, there's this endless stream of bad guys, like at least 100. The timer (and by proxy, your life) will run out several times while you figure out wtf to do. Even when they stop, there's still no clear answer what to do. Turns out, there's a rock in the back of the stage you have to beat up, and it opens a door to the next part of the area. There's several other of these rocks that are just background, so why the hell is this not? How am I supposed to know this?
