Feedback on the new version: The physics of the small black box has been greatly improved, and now there are almost no bugs when picking up and moving the black box with it.However, new problems arise in determining the trigger mechanism of the black box. If you put the black box completely into the black container it won't trigger the mechanism. To trigger the mechanism....., you must Angle the black box into the container so that it makes contact with the outer wall of the container and then angles into the container I've attached screenshots to show you what's going on
PS:I finally manage to complete the whole game. Walking on vertical walls feels terrible......
