Fun map, took me about 45 mins to complete. It looks quite intimidating, but it's actually fairly easy.

This was hard, took a while to pull of but felt relieved when I solved it. A lot of quicksaving is needed in this map to prevent redoing things.

Nice puzzle!There are some clever tricks,as well as a lot of change about position and angle with the cubes.I don't think it's intended,cause I used some angle-based lasers,though they are not tight at all.

Lots of head scratching on this one. Very clever puzzle. Really enjoyed it.

@lapicidas Oh, that's not good. I may have to fix that one too :)

In the first half I executed some moves differently than @Omega:

Another amazing map!! Took me three days of just going over and over in my head all the moves that can be done in this map. Finally found the right way out. Excellent! :steamhappy: faved and awarded

ok

@jandlml Interesting, but that move isn't in the book
jandlml 6 Sep, 2021 @ 8:52pm 
this seems to be as far as i can get. i can do this move with the cubes in either position https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2595622704
