Unfortunately, the most interesting flash Sonic game seems to have been lost to time. This allowed people to create their own Sonic levels, mainly based on assets similar to Green Hill Zone, but with a different colour scheme. Levels could be played by other players.
From the looks of it, the controls for playing the levels were quite good.
You can see a few fan levels being played here:
