Its obvious: when someone shouts "THE FLOOR IS LAVA!" you keep your feet off the ground!
Take up the Hot Lava Challenge and jump higher and higher. Climb on furniture to avoid your red, melting enemy! The higher you get, the better. But be careful, some furniture is tricky and makes you fall down. Collect coins and get helpful stuff, make your fingers red of tapping the screen.
Everyone knows that "the floor is lava" is a matter of honor!
