We made this game in 48 hours for the Adventure Time Game Jam http://www.adventuretimegamejam.com/ Since I'm not making any profit, I guess I can upload it here, like any regular fan art :)

So, you have to catch Ninja King. Finn and Jake always move in opposite directions. The trick is to get the two of them exactly one space apart on the same level or above and below the same box. The ninja king will always appear between them when you get them there. Part of the trick is to find places where one character can go up but the other can't go down, or find a place where one character can move left but the other can't move right. First two levels are easy :D

UPD: whoa guys thank you for all the faves and comments!! I feel so incredibly happy when you say you like it! ^__^
:bulletblue:For those who were wondering how many levels it's got - the game only has 8 levels, then they start from the first again.
