Yes there is, the special edition comes with extra features and content that the standard doesn't have. It includes free roam noclip mode, speedrun mode, allows you to play old test levels, allows you to choose over 100 levels to play, access to all secrets in the game including the unused ones, access to the Darker Places Album soundtrack with 70 music total, access to the A Dark Place 2 Sneak Peek preview, and A Dark Place + My Place wallpapers and a little thank you note in the readme file. This is used to support my newer projects in the making.
