this game was originally made for Playdate, hence the 1bit graphics and strange display size. this port is pretty much the same except the score is a different size, which doesn't matter at all. you can get the playdate version here.
controls: arrow keys. pressing any arrow key will send you one step in the current direction of the arrow you're standing on and change that arrow to whichever direction you pressed. pressing in the same direction as the current arrow will change the current arrow to an X instead, granting you one point but preventing you from landing on that square again. landing on an X or going off the edge of the screen results in a game over.
my best score i think is around 60, but the score pretty much just depends on how long you're willing to stare at arrows for.
