Sonic.EXE is a dark, twisted take on the classic Sonic games created for a gaming competition.
Sonic.EXE is, of course, Sonic.exe, a portable game that does not require installation.
The dev is clear that this isn't a full-on game, nor a great example of his skills. That said, he did update the game post competition so let's take a look at what he says was changed or added:
"This update brings a variety of graphical improvements, audio improvements, no less a few 'not-so-little' updates to the game world. There are some performance optimizations made to the game's engine to help the gameplay experience feel that little bit smoother.
Some old secrets still lurk but may appear different in form. Some may have even been replaced by new, sinister worlds where the influence of 'X' has spread. Explore, and don't think for a second that the path you've taken will remain the same - turn back, keep your eyes peeled for changes. You may be rewarded for your efforts. Well... "reward" might not be the word for it."
We're not sure all Sonic fans will dig this one, but you've got to try it at least?
