Is that....Ice Climbers with Touhou....?
Ok, seriously, there already is Touhou Mario, Touhou Megaman, Touhou Pokemon, Touhou Tetris, Touhou Soccer, Touhou Romancing Saga, Touhou Mother and soon there will be Touhou Zelda, Touhou Street Fighter, Touhou Mystery Dungeon, Touhou Disgaea, and what looks like Touhou Phoenix Wright, and once there was a Touhou Mario Kart planned. There even exist a Touhou I Wanna Be The Guy, and I saw parody screen shots of Final Fantasy IV with Touhou! And now there is Touhou Ice Climbers?!
Why is there no Touhou Kirby yet?! It can't be that hard! We already have a pink glutton and a crystal winged psycho in Touhou! It SCREAMS for a Kirby version!
EDIT: Oh lookey here, there's even Touhou Puyo Pop!
