I may just start using screens for guy rooms... Because he is NOT returning to the Return Point of whatever he warp he enters. He returns to Warp Point A, no matter if I set the return point of B to B or C to C. I'll likely never ever need to have more than one item room on a screen at once, I just really wanted to have him pick up the sword in an item room on the start screen, but can't make him exit to the right warp point.
I even downloaded a remake of the original to I could see how they did it... They used a green stating position tile -_- and the cave was warp point A.
