Fun, Fun, and more Crazy Fun :D
The first thing it comes to mind when you look at the logo is Flash Gordon, then once you are in game, you'll realize you're in for a lot of laughs as it will have satires / Easter eggs (whatever you want to call it), anything from StarTrek, to High Hiker of the Galaxy, to George Clooney, Red Baron, and many many other Sci-Fi classic comedies stuff embedded.
The actual game itself, is more like R-Type but easier or harder depending on the amount of crazyiness involved.
This is nothing but Madness, you can even expect flying Zombies. LOL :D
It's a great stress reliever, just sit back, have fun, and shoot stuff while having a good laugh.
IMO this game is a Master Piece ^_^
