@Denis Nazin The third law of B hovers reads “Hovering on a moving block can only work if there is only B. And the hovering effect will disappear if you do tap/cancel tap".
Now that's another matter! When you understand the principles and understand what needs to be done, then the game becomes fun and interesting. Thank you ! The most important thing that I could not understand : Spoiler is that you need to quickly remove the stairs! Thank you for the video. When it became clear what to do - the torment turned into fun! I really liked it.
@Denis Nazin Thanks for playing. I gave the video because I'm sure you can finish it. Because there were some players who asked for help, but after I gave it s/he still didn't finish it.
