A dropped a few stars for a few reasons. The Zapper Ball drop required Z to be unstable otherwise, Z wouldn't hit the ball. So if B arrived in the slot too soon and was still then Z wouldn't hit the ball but if B gets there just in time, then Z is wobbly and should hit the ball but Z may also fall off or not push the ball properly (not straight and you had no guides for the ball). One could also make Z unstable with the lift but that was much harder to accomplish. I won the 1st time with B and only needed one Z to drop the ball but of course B died. I also won with Z but again B needed to die (not a fan of that). The move also wasn't very stable as B often fell to the surface and Z didn't turn. I used auto pilot and I'm guess the Z win was the intended way.
@gmacpro i dont understand you, the first zapper must kick the ball, so you can get out and use auto pilot, then, you shall be fast for avoid the z, you can go aside the second z and carry him to the win
@nabuco - So, you are saying that the intended way is B will carrying a ZapperBot for 4 squares to the win. I just tried that and B dies on the 1st step every time. What I said was B does the auto pilot up and redirects the 1st Zbot to the 2nd Zbot and the 2nd Zbot goes to the win. This is achievable as I did it but the intended way with Z on B is extremely risky and I couldn't do it.
@gmacpro if you do that with care and slow is easy, that is the reason for the draggables in the floor
@nabuco - Thanks for the feedback and you are correct - the draggable does help. So I've upped my rating.
