It's an annual contest to find out the best indie games of the year. Developers can enter games into two main categories (Pro and Hobby) and also special categories, like one for jam games. Here's where it happens: www.thegdwc.com. The winners are chosen by a jury in October. Multiple games can be entered by each, so you can enter both of your games. Your new game sounds promising, so I'll keep an eye open for it when looking for the new releases!
