Does anyone remember “Skyroads”.. ? Orbit-Hopper is an up-to-date Skyroads-clone featuring OpenGL 3D graphics, enemies, new floors, highscores, new levels and much more. A leveleditor is included.
This is the first one of my 3D-projects - development began sometime in 2004 and the game has gone through a lot of changes since then. It was started as a Direct3D project, moved to OpenGL soon after being started and finally became a SDL & OpenGL based game.
Thanks to SDL & OpenGL this project runs both on Windows and Linux. Source-Code is available, so you might even be able to get it to run on MacOS.
