You are playing as "Old Man Gill"--a grumpy, old WW II vet. Late one night, a meteor crashed into your prize winning cucumber garden, and infused the cucumbers with a power that passes onto whomever eats them: the ability to see the aliens that have been living among us, and who want to take over the world! Use your powers as Old Man Gill, with some help from your helicopter-flyin' pal Gummer, to identify friend-from-foe, evade & kick out the aliens, and free Earth from invasion!

How to play the game: a 2D identify-and-evade game, where you as Old Man Gill manouevre close to NPCs with "question marks" as a clock ticks down. Once the timer finishes, the NPC is revealed as either truly human or alien. If an alien, run, because they'll start to chase you! Utilize various tools from rocks to teleportation to boxing gloves to evade and distract the aliens chasing you. Once you identify all the humans and aliens on the screen, a walkie-talkie will appear; once you capture it, you call your helicopter friend Gummer to fire missiles at the aliens and take them out in one fell swoop! Collect fruit and other treats to mix with meteor-infused cucumbers at home to increase your speed and other skills! Advance through various levels as you evade aliens of all types and sizes, with different weapons to take you out! Fight end-level aliens with epic battles, with your goal to reach the Final Alien who determines the fate of the alien race in its claws!
