on top of the win block there is grass that you can step on B. when it's on the grass B waits for L and then steps on L; but should fail and B falls down and win.. thanks @ohmytian
Very beautiful design!! I really like. An interesting find is the L bot stumbling on Z. After that, my B always falls. After rebooting, you have to wait a very long time until L approaches B. I'm sorry - I can't finish. Thanks for the beautiful design.
I also find B falls off when L stumbles, then it's too much to go back to the start. Maybe there could be a stair so B can climb back up to try again, or maybe it just needs a smooth surface so L doesn't stumble.
Spoiler: my win I waited for P but missed him, then another P came past so I tried to jump on him but fell. From there I could quickly reach the win block so my game was short. I did try again and got onto P but it was a wobbly ride. I managed to get the star ontop of the steps. But trying to get back onto P I fell and got zapped.
