Great level! I agree with @Block builder; the title was perfect. I can't believe you were able to utilize this trick in a level! In my experience, placing even 1 block could change the entire thing. The level was pretty easy, but it was great. Nice!
That's a wonderful use of this trick. I have met several times such a behavior but never seen it in a real level. Good job!
Ha, ha, ha... each time I think I have seen everything in Mekorama, somebody discover something new. Amazing! Thanks! It is going to be a matter of time to see new levels using this "feature"... you should name it.
@chemi Thanks to all! Yes it is your turn to make good levels with it! For the name of the trick, I was thinking about "the grid trick" or "the bishop trick" (as in chess). Maybe we should ask @nGord what he thinks about it ?
