Nemeshit

A horizontal shooter about going in the wrong end and blasting your way out of the other.

Ace space pilot Arnold Brownscheiss gets hit by an enemy shrink ray, loses control over planet Earth and heads straight for a man. Unfortunately, it’s the wrong end.

Now he has to fight his way through the whole human body, from the rectum to the mouth, and burst out and get back to the space war. Hopefully finding a way to regrow otherwise he's a bit f*cked.
