Gemini

Simple, but the idea was cool.
Thanks!

Fun idea. Claustrophobia in the passage may cause B to step on the slider, that's slightly annoying.

Liked the idea but as @Block builder said, claustrophobia was annoying and made me restart the level twice until I figured out what actually I should do.
Thanks!

| Interesting level. The way that each pillar falls flat on the wedges is very neat.

thank you again @chemi. sometimes simplicity is better than complex one.

thanks for rating and review, @Block builder. that will be my notes for next level to put vertical slider carefully in the low ceiling.

@ADM yes, thank you for rating and feedback. before i'm not anticipated claustropobia effect as i directly clicked on the draggable box where not low ceiling, but it will be my concern in the next level.

@cpw thanks, for great mechanism i learn some of your levels

@laurence.gr thank you for playing and rating. form follow function

Nice concept - thanks

@gmacpro you are welcome. less is more, right?

Very nice, but putting the slider on a rail would smooth things out. Still enjoyable.

you are right @Don G Rowe. i will uploaded that revised card in the caption tab, but don't know how to do. or maybe simply change my thumbsnail picture above?
btw thanks for rate and review.

Unfortunately you have to delete the card and lose comments/ratings. It's up to you whether or not to post a revised level. Some folks load a new card with number behind, like "Gemini 1.2"
