Ok, again, this is my first "tricks" level. Changed some flaws that @Block builder pointed out. Thx guys for testing, and sorry for a re-upload.
In case some things are too hidden... Spoiler: exit the cave once B enters the cave with red bricks on the floor, pull the dragable with a red brick underneath and look at the red cave right from the starting point. Just wait for B to appear there
Very nice level with many different and interesting steps. Perhaps some are too hidden but in general a great level, thanks!
