Any hint? It seems a really hidden level... Spoiler: What I did already... Opened both doors, lowered two pieces blocking R accesses, pushed the ball into the corner and moved the table for nothing at the moment...
So you finished it @chemi? I did what you did and it seems the intended solution. I like the design of the level, and appreciate the hiddenness from a design perspective and as a challenge.
@Block builder yes, it seems R had a weird issue and turned to the right before so I thought it was not possible such solution. Nice level although too hidden in my opinion... Thanks!
