You can download Enigma here.

This was made specifically for Mystery Tournament, a double-elimination tournament about racing to beat games neither player has played before. Because the default Enigma levels kinda suck (especially for the purpose of a fair Mystery Tournament race), I made a pack of my own. Though many of the levels reference in-jokes surrounding the Mystery Tournament community, the pack can still be enjoyed without that knowledge. You can watch it being played in the MT15 Loser's Semifinals here.

I have also included a beta version of the levelpack, with many levels from before the testers nerfed them into the ground. It includes an entire world which was cut from the game.

Installation

Windows instructions: Download Enigma and run it at least once. Copy the zipped level pack file. Open File Explorer, type %appdata% into the bar at the top, and press enter. Navigate to the "Enigma" folder, then the "levels" folder. Paste the zipped pack here. Note: if the "Enigma" folder isn't in AppData, check your HOME directory.

After you've done that, open up Enigma, navigate to Level Pack -> User, and select the installed pack.

Enigma, by default, plays no music while inside a level. Since this is kind of boring, from the main menu go to Options -> Audio -> Set the "Music in game" option to "Music in game".

If you must force restart a level, press ESC, then select Restart Level. Or, you may use the keyboard shortcut Shift + F3.
