Hi, this might work with the environment, but doorways are more suited to smaller units, although the average height of a humanoid character in the pack is 42 pixels (the sprite itself is 64 pixels), for example, an orc is 65 pixels (the sprite is 102 pixels).
I don't work on commission; after collecting a certain amount, I'll update the pack. You can email me your ideas via support (ponetisup@gmail.com), and I'll try to implement them.
