Shadowess

This dark and simple game has a sinister feel to it. it's a bit like Commandos with enemy sightlines conveniently displayed for you, but with the added worry that if you touch the walls they know you're coming.

The game advertises the fact that you need your old school keyboard skills to be at their best and it's true. You'll be scooting around the screen frustrating yourself for hours if you get hooked.

Use the arrow keys to move.

Stick to the shadows, duh!
