hard target

@Steven Maki You mean hidden zapper? I couldn't see any Z bot in this level even I used Meko Studio...

@Ray Aznable @Anomynous Did you guys need to use autopilot? Because I needed to use an autopilot in the beginning...

EDIT: How did you guys win? My way is too extreme..

Okay... I used an extreme way to win.
+1 star for being playable
+0 star as many elements can be not used
+1 star for the design
+2 stars for my extreme gameplay

Spoiler: Extreme win

I didn't use cancel tap, the top two balls, a mechanism and even R! (Well, R pushed the first ball. But that's it.). I used the first ball, the last ball, autopilot, long legs, BB and SSS.

@Steven Maki Any reply?

@Steven Maki The problem is, neither B nor R could get through the wall using the motor in my device.

@Steven Maki Yeah, I know, but you said 'hidden z' and I thought it was talking about Z bot, not the zapper mechanism.

@Ray Aznable Read my comment above. I can't...
