Tight Quarters

Here's a version without any trick. The rest of the game play is the same.

Spoiler: No Trick Required Version

Very good compact level. I had the same finish but a different start.

Spoiler: Alternative

i left zbot where he was and used B to herd pillarbot. Then got B to jump off , then moved zbot into place and autopiloted B back on.

@ridgerunner - And @ridgerunner finds another way yet again.... Thanks for playing and commenting.

Did exactly the same as @ridgerunner. Quite liked that solution.

@Block builder - The alternative method is safer as Z is way out of reach. It works for me too. Thanks for commenting rating.

I also seem to have discovered the @ridgerunner way.

This is always interesting. As a designer, it is so easy to get "scope locked" on your intended solution that you never see an alternative. So naturally, everyone else who plays your level sees and uses the alternative right off the bat!

@Don G Rowe - I could have added a row of blocks to eliminate this alternative route but it was a fun level none the same. Thanks for playing and commenting.

Excellent compact level. Thank you @gmacpro
