A, D, Left Arrow, Right Arrow - Move Left or Right W, Up Arrow - Jump The goal is very simple, just escape from the lava. Just kidding! There's more! You can press start to go onto the normal map or press the random map button to play a random map, but don't click it because most AI generated maps are impossible to beat, they can break the game too. You can change the lava rising speed as well, with 1 being the slowest, and 5 being the fastest. In the settings, you can change the friction to suit your needs. If you don't know, friction is the external force when 2 objects meet, basically slowing down the object. So, the lower value would stop it very quickly, higher value less than 1 would take longer to stop (Unless it hit an object.), a value of 1 would neither stop or speed up, and anything over 1 would just speed up until it hits an object.
Note that there can still be glitches in the game.
