I like the combat idea overall
The main problem is your ui has the same hue/saturation with map, blends in and ends up completely unreadable
The action options scale with the map and thats bad
Prebattle placement should be drag n drop I think
Also maybe you should add big ui sections on screens sides showing what is going on and summarising like This guy will use this action on this guys etc
Got random stutters while traveling the global map
Liked the dungeon section
