Ball Riding Demo

Haven't actually played it yet, just looked at the screenshot. The first one is easy - tap the red brick immediately, and B will (hopefully) ride the ball across the fence. @vince used the same thing in his level "Across the Moat" (not across a fence, though), and I used it in my level "Funny Ninja B", but in both those, the ball came up from below rather than dropping from above.

Just click the red brick at the beginning, this is not a device.

The three ball riding devices collected are as follows:

1. It is composed of two eyes, learned from @huijiuggbf . Simple, practical and stable, but not very attractive, it is difficult to integrate well with the style of the level. It usually covers the upper eye, but the lower eye has nothing to do.

2. Push the ball with another ball. It takes up a little space, but it's still easy to use.

3. Sensor. The advantage is that it is compact and practical, but the disadvantage is that it is easily triggered by mistake. This level has been protected to a certain extent, but @XSHY can still be triggered in the spirit mode; and I also set a trigger ball in the level, if you push the wrong ball, it will trigger early.

Spoiler: Hint

1、Was it coquettish at the beginning to ride back on the ball? It's not this way to count my friends.
2、The red brick can not only indicate the location of the ball, but may also indicate the entrance and exit of the underpass.

Can't solve this, but @935, why do you make your levels with big QR codes? (some of them) the first ball won't fall correctly on mine.

@D.S.Masters
Very good structure, but my approach limits the timing and improves the success rate.

@Blue Tower
Convenient mobile phone to get the QR code on the computer screen...
