Many folks wondered why I chose to do a collection of puzzles and not another metapuzzle.
It was a financial decision. Due to poor marketing, TFE sales were terrible for the first eight months. Then Neil Shapiro wrote a stellar review of the game in MacUser (followed by many others). And that's when sales skyrocketed.
But those eight months were lean times.
Miles Computing suggested that I do a Puzzle Gallery, a reusable puzzle engine, that could create a series of games using the same ten puzzle types from TFE, but with the data-driven capacity to add new art and puzzle variety.
I needed the cash, plain and simple, and so I took the contract.
That being said, I did enjoy making the game, and to this day, I still chuckle at the goofiness of it all.
It should be noted that in order to avoid the storage space limitations of 256-color bitmaps, I developed a graphics language to draw the images dynamically.
