eryi's action is awesome,it often trick you into moving in a certain manner or do something that you would find it obvious and then make fun of you for doing it usualy by killing you in a "take that,player! bet you didn't expect that uh?" fashion...
it's more like that sega joke game (pole big adventure?) than i wanna be the guy since once you know something is there it's (usualy) pretty easy to dodge but it's pretty short and frankly not worth the value other than for a cheap laugh
yes,this gif sums the game pretty well,if you ever watched asshole/kaizou mario it's like that but more centered on the "ah-ah" part than the one that are just plain hard
