About
The core of the game, the puzzles, are finished aside from any tweaking that may happen before full release. Most of what's left to complete is getting all of the placeholder art replaced, working on the sound design, adding music, and general polish.
Buying the beta will get you access to all beta versions, and the full game once it releases, including a steam key once the game is on Steam. The beta is also at a discounted price! The full version will be more than $6.99.
