Instructions are shown in-game but I'll put them here. Play vs a bot - Choose rock, paper, or scissors using buttons or A, S, and D keys. Play vs a player - Find someone to play with. Player 1 uses A, S, and D keys, and Player 2 uses left, down, and right arrow keys. The background music gets higher pitched as Player 1 scores more points I'm pretty sure this doesn't have any glitches ...except the one I unintentionally created that I'm not going to fix because honestly it makes the game better (press See Inside and go to the Player 1 sprite to find it)
I got the background music and explosion sprite from @tiny-pig
