Thank you for playing and noticed this alternative way Kimist ! For my defence, i can say it's my first test chamber ever, BUT, i have updated it at the ending of the last year and still don't see other solutions...Well, now with your explaination and maybe my better skills in chambers building will give me the tools for fix this one :)

??? I never accessed the area behind the red laser shields. I got the cube and placed it on the button, then the exit door opened.

Thank you Stormsend, i will be happy to play your test chambers :)

Pretty good for a first. I will be playing through some of your hundred or so. Try some of mine when you can. See ya round the workshop.

Ha ha ! My first (and very not the last) mistake :) Thanx for playing my first try.

haha your first chamber is very funny but it has unintended solutions xD.
