What a great game

This is great to challenge your mind everyday. It makes you think about approaching problems from different angles and methods. Ive found one of the best ways to solve some of the puzzles is to work backward especially since once you change a color its impossible to change it back If youve tried the free version then the full version is worth the 1.99 since it had all the community developed puzzles.

One thing I would suggest is a method to clear the entire board as well as a method to test the puzzles that you create to make sure theyre placed in the right difficulty level.
