The Kickstarter for The Shapeshifter has already been a success, and the game is officially coming to the Game Boy. The campaign also hit a Kickstarter stretch goal to include some extra content. The Kickstarter still has plenty of time on it, and stretch goals to hit. You can pledge to the Kickstarter here, and read up on the game boy.
The Shapeshifter puts you in the shoes of Elliot, an ordinary person who is going to spend the weekend in the mountains, who meets an elf that will grant him the power of becoming the animal he touches.
