Frankly, I'm hooked by the shear visceral side-scrolling action. The basic movement mechanics (leaping, rolling, rocket-boosting), when combined together, enable players to cover more ground and capture enemy bases quickly.

The level design also helps the player escape the opponents' line of fire when maneuvering around obstacles, which could also be a hinderance to those who find themselves in a dead end.

One thing I have yet to try is adjusting my own keybindings so that I could naturally aim grenades with one of my mouse buttons... I believe the Steam version enables re-binding.
