Indie developer Nicolai Troshinsky has created a neat little experience for the Experimental Gameplay Project's "Zero Button" challenge this month. In UFO on Tape, players have spotted an alien craft from their car, and must use their mouse to keep the camcorder trained on the ship -- if you lose the UFO, your camera's battery runs out and the game ends.

It's a simple title, even more so than Orisinal's similar UFO game The Truth Is Up There released nine years ago, but the grainy graphics, distant buildings, out of focus elements, and sound effects (e.g. cars driving by, turn signals) really capture the feel of those amateur videos you often see in documentaries about aliens. You can download UFO on Tape for free from Game Jolt.
