Hey, this was fun. Linux version worked perfectly. A very simple concept that you executed really well to make a fun little puzzler that kept me thinking. I thought you had a good mix of easy and hard puzzles, and each puzzle seemed to have a fairly clear way to reach the goal once you were able to look far enough ahead. Some of the puzzles in the second half of the game get a little cluttered with so many coloured block, and it’s sometimes a little hard to keep track of where the flags are, but overall I thought you did well with this puzzle game :).
