Thank you so much for your feedback!
There really is a lot of training in most games nowadays. It's a kind of reference to the games of our youth, when you had to understand the rules or nothing would work. Apparently a bit overdone.
The first two blocks give hints. If you look closely at the animated blocks at the beginning, they literally say, “you stand here, listen to music, you wait a long time, you die”. Perhaps the game is ruthless in that once you run past this clue you will never encounter it again.
On the second block, the “evil” blocks are marked with a skull. The ones on the left are white, the ones on the right are black. Spoiler, this rule will remain in place for the entire game. Yes, there will be more levels waiting for you when you reach the end of the track)
We hope that these hints will help you to solve the secret of the game
