The depth drawing issue of the starting tile is now fixed. Seemed to happen when dying on a boss level (after opening the chest ie. shuffling the starting tile back to deck).
The lack of room for bigger levels is annoying. There probably isn't anything there on the right side as the levels have max width and height so that it should be able to show everything. I guess in this case it should pan the camera left a bit to show the edge of that too because seeing even half of the yellow pylon here would be enough.
I've been toying around with the idea with removing the size limitations completely and making the camera movable by player.
