Thanks to @gmacpro , @delator77 , @GFJ for the playing a previous version and find a error...i hope this okay now..
Very fun tricky/logic level..nice design and path...I really like the ball kick step,very stable,the balls always went to the right "hole"Thanks for sharing @Źàiď Btw,I had a doubts...in the previous version you was able to do the last step or it was an error?
Thanks for fixing that. On my 1st attempt, R wouldn't knock the ball by the zapper so B needed to push R on/at the stairs for the ball to go. On my 2nd attempt, R got the ball without help from B. If I remember right, the same thing happened in your last level. BTW, I used the following tricks: Spoiler: Tricks SpringBoard Stairs, claustrophobia, and auto pilot
@delator77 nope, i don't try it i just realized when you all find a error...i think i need try it first before post , right?
