This is a test of different undertale characters' abilities (basically I wanted to see if i could program Sans' abilities and then it just spiraled from there). Here are the controls for every playable character:

Sans: W,A,S,D(movemeant) G(gaster blaster) B(bone) M(play Megalovainia) X(Swap to Papyrus)

Papyrus:W,A,S,D(movemeant) B(bone) G(throw Spaghetti) X(Swap to Sans)

Chara: Up,Down,Left,Right(movemeant) {/}(throw knife/eat chocolate) {"}(swap to Frisk)

Frisk: I,J,K,L(movemeant) O,U(mercy/fight) {"}(swap to Chara)
