Jigsaw! (GS/OS)

Jigsaw! is a simple puzzle game developed by Huibert Aalbers with Javier Rullan Ruano that was published by Britannica Software for the Apple II GS.

History
Programmer Huibert Aalbers said that he wrote much of the game over a weekend and that it had sold over 100,000 copies.

Deluxe version
As Aalbers was unsatisfied with the initial release of Jigsaw!, he proceeded to work on Jigsaw Deluxe with new features, such as music, 2-player competitions, and more complex levels. However, the Apple II GS market was in decline and Britannica Software was in financial trouble, so it remained unreleased until November 2016.
