Sure. Now I get it. I had to hit that rock when I got that tip/message. I will try it again later.
You can post my video anywhere you want. :D I enjoyed playing it.
Thank you for your response.
P.S. You can give an additional tip for a player after the sulfur point. For example, if someone would go farther than the sulfur point and miss it, the game will send them an additional message.
