The Floor is Lava is a "fast-paced" puzzle game where your objective is to clear the levels as fast as possible, as you are trying to get out of this nasty pit with lava rising up from beneath you. If you don't do it quickly you are literally toast!
The game mechanics is pretty simple: Trace a line from the "starting tile" to the "ending tile" while passing through ALL of the tiles without crossing your path (i..e. no backtracking).
The graphics are pretty decent, for a puzzle game. While there's timing, the timing itself doesn't affect the game THAT much.
Definitely download the free version to try it.
