This is the original flash prototype of Closure.
After releasing this here on Newgrounds, we spent 3 years making a bigger and better commercial version of the game from the ground up in a new engine.
It is NOW AVAILABLE ON STEAM and you can check it out here
The new version of the game is better in every single way. The graphics are better, the music is better, the gameplay is smoother, the puzzles are less frustrating (and there's nearly 100 of them!), there's new mechanics, new features, new characters, and hidden silver moths to keep you busy for a long time.
