That is a forum adventure called Problem Sleuth by Andrew Hussie. He is also the creator of Homestuck. Have you heard of that? Problem Sleuth is a fantasy/sci-fi adventure based on Great Depression-Era Niore movies.
lol. i like this. it reminds me of something i've seen before but i cant quite pin down what it is. maybe its that super mario game for like nintendo or supernintedo where it actually allowed you to play as the princess or Toad. nice pic.
