Really neat and fun puzzles that are rewarding when you figure them out. With some cool Vsauce soundin ass music to set the mood. My biggest problem with the game though, is the hints. They sort of ruin the challenge, which is the whole point of a puzzle.
Slight conveyance issue at level 15, the screen flashing like that is usually a sign of the level resetting, so I thought I wasn't making any progress at all. Eventually I just used the hint, which of course made it super obvious. The point is, I never had the thought to break down the numbers I was clicking because I was certain that no matter what I clicked, it reset the level.
Level 25 was my favorite concept, but was way too easy the way it's implemented. All the colors required the sliders to be all the way left or all the way right. It would have been fun to use more precision in selecting how much RG or B to blend by requiring more complex colors.
Anyway, overall it's a great game, but would like to see more complexity and less hints in the future
