This seems like a good thread to dump these in. I made a game called Love+ (it's on
Greenlight,
Desura, and standalone at
Level Up Studios), and I've recently updated the Desura build with the full custom level editor set.
The game is very simple. It's a traditional 2D platformer with very minimalistic graphics, but its charm comes from the gorgeous soundtrack (by James Benett) and a neat respawn mechanic. You're given the option to place a checkpoint at any time as long as you're on solid ground.
It also has a custom level creation set I call Love+Custom, which allows you to make a level by drawing it in any of your favorite image editors. You can assemble up to 10 levels, and redistribute them to your friends in a nice little package.
Here's 10 keys, first come first serve. Desura activation only, of course.
I hope the ten people who get the game enjoy it.
