this is actually a game a made a few years ago. It's a remake of the special stage from Sonic 3 for SEGA Genesis, back in the 90's. The original minigame is called "Blue Spheres", and for the time it had a great pseudo-3D graphics. What I attempt to do is to keep the original gameplay and but give the game some modern 3D graphics.
The project got larger as I was making it. Here there are the main features:
All the original Blue Spheres levels (about 128 millions) playable by typing their 12-digit code
A simple level editor, which will allow you to build your own custom stages
3D and Full HD OpenGL-based graphics engine
Built-in interlaced stereoscopic 3D support
Remastered music and SFX
First person ("headache") mode
It's free of course, and also the source code is on GitHub. Here there are some links:
