Sneak In V

Super clever on many fronts.

Spoiler

I think this is the first time I've seen ball trigger a slider/block move in a level. The part with fake B-Bot dropping a the real B-Bot rising was really cool. Finally the R-Bot's push of bar at the end was just great.

@chemi Just so you know, there are some "bugs"in this level.

Spoiler

The 2 slider bars which freeze R-Bot are technically bugs. Some might argue that R-Bot pushing 3 blocks at once is also a bug. The duplicate B-Bot was created a bug in the game, but that's really a cosmetic rather than functional thing. Most really good levels utilize some bugs in some form. I drives me kind of nuts when complain about corner case physics in the game... they're certainly there but they are heck a lot of fun to design with. They make some of the really amazing stuff possible.

Actually, I have used ball-triggered slider mechanisms several times already, although I usually keep the mechanism hidden so it may be hard to notice. Some examples: Selling Machine, Ghost Town, Three Jumps

B should revive after you push the correct balls into the holes (not including the starting ball), and there is a hint for which balls are correct. B shouldn't revive by itself, but maybe the mechanism could break on rare occasions. I tested it many times and didn't see any anomaly.

The best level I played in Mekorama so far
Besides the admirable mechanism the level design is impressive: looks easy but is difficult in every detail. As always nice built-in hint. Though it has everything a level can have, and at its best. Equals addictive levels in classic games

Awesome level, no tricks or bugs. Amazing to see B without a head and how to recover it. How do you do it, @richardfu_? Anyway, thanks a lot.

WOW!!! Without doubt one of the best level I've ever played...ability, trial and error,timing,strategy ...nothing hidden...GREAT

Multiple Attempts - Code Can Not Be Read

Really fun level to play. I loved the effect with B.

This really is one of the best levels in the forum! The mechanism, the design, the collaboration, the puzzle, the multiple purpose use of the elements, the surprise!
Great, simply amazing. Thanks!

@DreamBliss Here is a clearer version!

Brilliant finish to the series! One of the most innovative levels ever created!

Evergreen level...
I believe that there is no great level than this...
