I couldn’t resist making my own 2048 game, using images from the Girls und Panzer movie. Beware: this can be terribly addictive, and if you have work that must be done, do not click here.
Update: I made another one using images from GATE and a different online game maker.
(If you are unfamiliar with this sort of game, you play it by using the arrow keys on your keyboard to push the tiles around. There are eleven (2,048=2^11) different tiles; revealing the last two is not easy.)
Update II: There are orchids now, too.
Update III: And ballet.
