Tap-2 16

I've already asked @935 to prepare the video. Special thanks to @FXCX for this video.

Spoiler: Video

...
wonderful design...

What? 18 minutes to solve the level?

@delator77 ..thank goodness you opened the video and saw the duration as i was still working at this level but have instantly stopped. I was quite enjoying working through the possibilities but it’s far too long. I watched enough to spot the two balls on the stair which was a clever move . And that hidden zapper was totally over the top, when there is so much to be considered.

...
still done halfway
and I ended up postponing this level,

even after following the video precisely
i still did some mistakes like accidentally zapped
and got tired to restart for more another
long minutes of gameplay...

although,
this long advanture is still good to be kept
for somewhile...
give me some goal plan to reach further...
will try to solve it again later...
