Clik the down arrow to move down, and click the up arrow to go u for player two, and for the first player, it is w and s.
This is Update 1.01, i'm sure the interface looks TOTALLY different, by the way, I should give a giant shoutout to the scratcher called @benji2007 for completely developing this project. So the interface and everything was by him. So if you are seeing this @benji2007, thank you soo much. Plus, there are so many bug fixes. And @benji2007 also helped make it a two player game.
