I have no interest or enjoyment of internet culture, so all of the YouTube trolls are just irritating to me. Got past that bit, found the game design to be quite interesting and somewhat refined.
This is a game where failure is a necessary step to the learning process to progress. However, for reasons that I cannot quite comprehend, you have decided to add a life counter. In my opinion it completely ruins the experience. I had no intention of committing prior levels to memory and execute them again with backwards controls, so that's when I stopped playing. I understand this was the intent of the game, but I play games for entertainment. I don't get any enjoyment from solving somebody else's deliberately annoying puzzles if excessive repetition is involved. I like to see new content and solve problems, but not repeating areas.
Graphics are consistent, which is good, however, they are basic Unity primitives so...
There's no audio.
The theme was capture from various perspectives and fairly well.
