Fire and Ice
Here is an interesting on-line game for two players and for a single player as well. Main heroes here are Fire and Ice and if you play alone choose anyone you like.
On each level live dangerous monsters, but they can be destroyed easily with fire and ice cubes. If you run into a monster you lose one life one from nine. Another dangerous things are ditches with water jump over them otherwise the level is immediately finished. Along with obstacles you will meet bonuses red and blue crystals. They can change your weapon for a while. To Fire blue crystal gives ice cubes and for Ice red crystal gives fireballs.
