Bugging Out - Shooting Bugs

This is a very unique underground shooting experience. Shoot your way through the rocks to get to the insect bosses & show them who's boss. The rocks all have numbers on them which correspond to how much life points they will take away from you if they hit you. You can gain boosts along the way that increase your health and firepower. How many levels can you get past, and are you bug enough to unlock every bug & max out their stats?
