RPG Maker VX Ace

Core Engine

I created a simple battle system that basically makes the game slightly harder while adding more scripts to add on to that difficulty, when they come out you can add scripts to add on to the already kind of hard game... In these screen shots i am using the yanfly engine (which is compatible) so only focus on the menu commands.
as you can see the script removed the run and item commands from the battle menu. Other scripts will add more difficulty but this is being kind of easy.
