Thanks rO. I'd intended posting some games but I've had problems with the two computers I use virtually all day. :).

Looks like there is no game giveaway today so here are some games. These games were all created by Locomalito.
I recommend 8bit killer, it's has great NES style graphics and gameplay. All the information below is from the website.

8bit killer

Prepare to feel the 8bits as they felt years ago! 8bit killer is a first person shooter styled to resemble a NES game in look and feel.

AD 2488. A long war has put human race on the edge of self-extinction. Four years ago, a space creature known as Master Brain arrived with the promise of a new dawn. Now, a huge army launched an attack to the few cities that are still on, following the plan of the creature. A small group of soldiers have formed an alliance to defend those cities and kill the master brain. This games tells the story of their final mission.

32x32 pixel textures, 64 color nes palette and 1bit sounds make this game look like an early 90s game. The soundtrack has been created by the genius RushJet1. The story, characters and scenes are inspired by films like Mad Max or 2013: Rescue in LA and by games like Contra, Megaman, Bionic Commando, Metroid, Catacomb 3D or the sequel Wolfenstein 3D, and many others...

Zneik

A version of the classic Snake.
Eat apples to grown and move around without colliding with your own body.
Make yourself as big as you can. Easy and fun.

By the way, although this type of game is often called snake, it's really based on light cycles of Tron, what a classic!
