This game is inspired primarily by ZiGGURAT, Outpost Nexus and SpaceInvader! The news ticker is inspired by Super Mario Sunshine. The tractors are inspired by Team Fortress 2. The environment is loosely inspired by Return of the Invaders.

Defend the lone frontier town, Crater Bulb, from these brightly coloured invading ships! Bounce shots off the floor of the crater to attack airborne and ground foes alike. Charge up to fire one of three different shots, each with unique abilities and purposes. Beware: if even one enemy trooper reaches the city, they will immediately surrender! Undoubtedly, heroic sacrifice isn't the Crater Bulb citizen's top priority.

This is just a ripoff of Vlambeer's Ridiculous Fishing. Sorry. I saw how lucrative ripoffs of Ridiculous Fishing are, and I couldn't resist.

You can even tell by the way it's divided into two parts - one part catching a large number of things, one part shooting the collected objects in midair.
