Destroy KABOOM!

In the distant future, aliens have been spotted on Earth.
 Legendary war hero COLONEL KABOOM makes it his mission to terminate every last alien before they begin to spread.
"It's Kaboom time, baby!" - Colonel Kaboom first words on Venus

In this game, you... play as the enemy? Colonel Kaboom is making his way to your headquarters and the fate of the alien race is on YOU. 

The troopers you have are:

Codename: TRAPPER

Very weak but very fast. They're able to leech energy off of Kaboom and give you more energy to transport more troopers in.

Codename: KERNEL

Average in everything and able to throw corn. They can also claw using their sharp fingers which leeches a bit of energy.

Codename: POTBELLY

Has tons of health and shoots seeds rapidly. However, their movement is restricted due to their pot and is unable to leech energy.

Codename: FUNGLER

Able to wield magic and attack Kaboom at almost any range, leeching a bit of energy as well. If Kaboom gets too close, they also have the ability to teleport.

Strategically use the four trooper types to overwhelm and, ultimately, DESTROY KABOOM!
