Very simple game that isn't over complicated and easy to piece the clues together! I think this would have been a really good tutorial or early stages of the game. I think adding a ramping difficulty would give the player a reason to continue challenging themselves. I caught myself getting bored around 600 score since I unlocked the pattern at that point, which I think would be a good point to add newer elements or increasing the difficulty. Overall, enjoyable game! Rated!
