Assuming you're referring to the org and not the rope (which looks exactly the same as the one you showed me yesterday), nice job! And iirc, yes, 40x40. I think, however, my earlier idea of having solids be polygon-based might overcomplicate things, and maybe we should do tile-based and only use 45-degree slopes? I also think my earlier idea of having the player collision shape be a circle may be a bad one.
