Thank you for the reply! I'll see what I can do later

Hi Briar, In the Luna Caz Demo, there should be a setting in Menu Status that shows how to do vertical display for gauges! Here is an example:
BattlerHPGauge:
type: gauge
x:
type: fixed
value: 13
y:
type: fixed
value: 408
anchor:
x: 0
y: 0
pivot:
x: 0
y: 0
rotation: 270
bind: true
width:
type: fixed
value: 291
height:
type: fixed
value: 46
I believe it's rotation that controls it.
