Not much, just a couple sprites that update their position on the screen using cloud variables. It also has a click detector. The purple cursor is P1 and the green one is P2. Press 'r' to reset cursor positions. Press '1' to say "Hello!" Is kinda buggy right now, though. This thing also lags a tad on mobile. I think. It does on my phone.
Update Board: 10/19/2020 -- Project released. Somewhere between these 2 times -- Added cursor mouse-click detector 1/8/2021 -- Added cursor pos. reset function, fixed single- user bug where if one user is present, the second cursor disappears behind the "P1 Mouse down?" Variable. Added a "Hello!" message function.
