Chapter - Hard timing

Then I forgot about it, because it is a “difficult timing trick” and that’s why no one uses it at levels. But you are braver than me and you were not afraid to challenge the players. A very cool and hard timing trick - that’s why it’s better to give this trick at levels in such a way that you can repeat the attempt several times! But at your level there's only one chance

@delator77, thanks for posting the solution. I noticed you used Google photos to post the solution, I was not aware of this with videos, but I had a little play around and I think I know how to post my own solutions now, thanks to you .

@RonaldN, thanks for rating. Glad you managed to complete it! Thanks for playing

@Denis Nazin, thankyou for rating. I wanted to say, I only saw your very first comment now asking for the solution, before I only saw your second one. These are interesting demos, same type of trick but different setup method! Yes, I was happy at this level to include that trick without retries, as it is half the level and so it is not a lot of extra effort to restart the level. Thankyou for playing as always my friend
