Makes me wish there was built-in proper on-top-of-Juni tiles in KS+.If you're referring to having a layer for tiles which overlap the player's position, KS+ does have that! You can use the "Overlay" feature to make all layer 2 tiles stay on top of Juni and, well, everything else.
Hah, well, it seems I haven't used the editor to its full potential yet, then! :P Still cool, nonetheless.In the Misc tab check the Overlay box. Layer 2 moves between layers 6 and 7 for that screen. Be careful though. Nothing on layer 7 will collide with anything on another layer. So, water on layer 7 wont kill. Creatures on layer 7 will ignore collision tiles on layer 3. Stuff like that.
