This is an exact clone of CK 4 done in QuickBasic. This game will feel almost exactly like the originals (except for the fact that you slide a little). The levels look exactly the same as the ones in the original, and they even have the same secret areas. The downside is of course there are no new levels or story, but it does feature a level editor (in my opinion extremely hard to use). Both the game and the editor take a LOOONG time to load though. Check out the guy's website for more info.
