Will sit on the Xs till someone else complains as well. Or I might add a setting for them to instantly fade in. Will add a fade out-in to the end of the animation so you can see underneath. But I also plan on adding a mouse-over tool tip.
Wall-allies can already push objects. Wall-player is already possible but it needs to have its own food clock and I've yet to figure that out.
Multi-enemies are cool. I have added it to my todo list. I might be able to use the code that operates hooks to do it.
Bullet enemies are already a thing. About level 4 I think. A bullet-spawner is effectively a turret.
Flee enemy seems like a given. But it needs something else to spice it up - a reason to chase it.
Conveyor belts require a second layer of data. Right now it's completely flat, with two rectangles that define a container around it. I already have the scroll-block working though. That shoves an entire row or column of glyphs - it wraps around the current room it's in. I just haven't tried it with doors yet, because it's going to be pretty bizarre rolling a door into the middle of the room and opening it (the logic still opens a room outside of the current room, it walks from the door's direction till it hits an edge).
