All-in-one program for creating 2D scrolling games. Compile your games into stand-alone .NET executables or customizable C# source code. The IDE and framework are build on OpenTK, which wraps OpenGL, so generated games can be cross-platform.
LinkSphere is being developed using the the Open Toolkit Libary (OpenTK) as an Open-Source RTS/Shmup/music-game, inspired by Darwinia, Gate 88 and Rez.
