Game is funny, full of action, with good music... but it's short and some graphics look like a Jazz-fan (not elite one, average one) made them. Anyway, the action is something like Jazz Jackrabbit + Metal Slug + Duke Nukem 3D. The Dark Shell is very comedial character. You've seen that red "Do Not Press" button on his armor? When you shoot it, his pants fall of and he cries mangally. And one of his texts:

"Here are my three steps of Jazz's doom!
..........
..........
Wait a second, I wrote it on a napkin somwhere...
Ah yes! One: Kidnap Zoe Cottontail and hide on Chelonia IV;
Two: Wait for Jazz as he gets to you in his spaceship;
Three: Destroy Jazz and become the master of universe!!!!
Mwahahahahahahaha!!!
Mwahahahahahahaha!!!
Mwahahahahahahaha!!!
<>"

Like it? There are much more of texts like this. Just play the game!
