The third annual JayIsGames Flash Game Design competition - themed "Replay" - is parading the entrants as we speak. It's too late to enter, but you can play the games and vote for the winner of the Audience Prize. The first and second prizes are chosen by JiG reviewers, but the Audience Prize is chosen by PayPal donations of at least USD $1.00 and can add quite a jolt of cash to a talented designer's prize. Alternatively, it can do Great Justice for a designer who for some bizarre reason wasn't chosen by the staff judges.
Here's some of my picks from this year's entrants:
Karma fuses the concepts of reincarnation and the Western 7 Deadly Sins to create a game where the aim is to clear your sins and reach salvation with as few reincarnations as possible. It has a few bugs which can make it frustrating to play, but the music, sound effects and visuals are gorgeous and soothing enough to prevent you from hurling the keyboard through the monitor.
Tonypa's Yalpeyalper is a simple but cute game where you need to eliminate all of the squares in the grid by setting off a chain reaction. Be careful, though - if you're wrong, you'll end up having to replay all of the levels you've previously won.
In Paracaidas (parachute in Spanish), you guide a parachutist safely to the target. It doesn't sound like much, but it's beautifully designed and fun to play.
Wouter Visser's Gimme Friction Baby leaves it to you to work out how to play it. Once you do, you simply MUST go back and try to beat your high score... goddammit...
In Timebot, you stand on panels to open doors, etc. Then you kill yourself and reincarnate to actually go through the doors. It's a pretty cool game.
If these games don't do it for you, there's plenty more at JayIsGames!
