Fire Geysers

I've been a little bugged with my platformer game recently because the lava pits are generally too easy to jump over, and the lava wave is far too easy to avoid. To make things a little harder, I started the lava at a slightly faster speed and additionally I have its speed ramp up faster.

I also have added a new obstacle to the game: the Fire Geyser. This obstacle is a little mound on the ground that spits flames that will kill the player if they touch them. As a warning, the geyser shoots out a puff of smoke twice, then the flames shoot out. The smoke doesn't hurt you, but simply serves as an indicator that the flames are coming. It repeats on this cycle in a loop. Some times you need to run back and forth to wait out the flames, and since you cant actually stop running the closest thing to standing still is switching direction fast enough that you don't really go anywhere. Here are some pictures of the Fire Geyser in action:
