Although I didn't feel anything was super original in this game, I loved the simple meta shifts and difference in each traffic light of how the numbers went up or down. The texts on the side gave it a bit of a compelling story push to keep me going.
I liked that the balance was quite good - slow with a feeling of progression at the start, but also sped up significantly later on to let you finish the game. I ran into a couple of bugs (or it's just really unclear what to do), where I was completing the red light, and suddenly got back to green one, and I had no way to get back to yellow one.
