A really nice level. I love levels of this type, quick to play but not trivial. Then the mechanism on which the level is based is truly original. As @Denis Nazin said: Spoiler B on the mobile platform is a bit unstable and can fall off easily also causing victory. But this kind of mechanism could be perfected.
@Robot B yes i was hoping to make a diagonal slider,turns out its imposible..yes this could be perfected..
@AJX My friend, you make very interesting levels. And most importantly, you always do something new and original. I see how you make discoveries at every level. It is very cool! Well done.. You are interested in the diagonal slider in your comment, so I want to help you. Tell you what I have already seen (maybe you will be interested) When I started playing your level, I immediately remembered another level of another very talented author @d'SUKI (he makes excellent mechanisms). It has a level with an automatic diagonal slider. http://mekoramaforum.com/media/corner-roamer.23390/ It is similar to yours, but it is automatic (drives itself). But on yours you can twist - this is also a big plus. I'm sure you'll like it. I recommend that you get to know this author. He is somewhat similar to you (sometimes).
