This is the same as both 2.0 and 2.1 versions of Slime Volleyball. This version however has has both games combined with a menu and optional difficulties plus new music, background and slimes. There are a couple glitches however, like how sometimes the ball will go through you if you are jumping, but that can be resolved by jumping sooner. CONTROLS: Player 1- Green slime: Press the left arrow to go left and the right arrow to go right. The up arrow key makes you jump. Player 2- Red slime: Press the la' button to go left and the 'd' button to go right. The 'w' button makes you jump.
