These puzzles are presented with no explicit instructions or objective. That might be to your liking, especially if you have experience with puzzle hunts. Otherwise, highlight the lines below for optional information on how to get started, from least to most revealing:

1. Each black area on the spreadsheet is a separate puzzle. There are 15 puzzles in total.
2. The answer to each puzzle is an English word. Puzzles linked by black lines are somehow related, but have separate answers. 
3. One of the 15 puzzles is a "metapuzzle" which requires the use of the answers from the other 14 puzzles. You can consider solving the metapuzzle to be the "goal" of the puzzle set, if you want.
4. Each puzzle, other than the metapuzzle, is a method of compressing or encoding the physical shape of letters. Therefore, each puzzle, other than the metapuzzle, will involve physically spelling out the word.

I made this puzzle challenge to scratch an itch for puzzles in the style of Wizardoffail and Parachor, creators of Ultraviolet Puzzle Challenge. They started making puzzles in isolation from the wider puzzle hunt community, resulting in a unique style epitomized by colorful, wordless, pixel-art diagrams. Here, I tried to pay homage to the visual language of their puzzles and avoid many of the idiosyncrasies that make puzzle hunts less accessible to newcomers.
