Labyrinth ($$$)

I still don't understand how Gunar manages to reach...))) Explain.

It's better to see it once. Saves. In reality, it was very difficult to achieve this result because the entire game was based on millimeters and fractions of a second. If any questions remain after viewing the saves, I will gladly answer them tomorrow. Ideally, a detailed description could have been made, as there were many subtle points. But it seems that no one is particularly interested in what is happening here :(
