Generic, at best
This was pretty awful. I don't see the fun in the characters constantly talking about how much the game itself sucks ("lol the game designer is lazy", "lol this plot is cliche"), or how much other things suck ("lol anime."). I understand that it's supposed to be satire but...it's just not entertaining. It's nothing I haven't already heard from every other adventure game parody. Most importantly, the game play is slow and bland.
As for the positives...
I did smirk at the pit joke. I also liked the tree enemies, they made the game more exciting. The graphics and music are pretty nice.
