WVVW is a homage to the Terry Cavanagh's excellent VVVVVV game. It was developed in 48 hours for Ludum Dare #27 game jam, using C# and XNA (with my Flai.XNA library). I developed also an built-in editor for creating the levels.
You can download the game in the Releases tab. Requires XNA Framework Redistributable 4.0
