I'm not an RPGmaker expert, but I heard this game was very unoptimized. Something I noticed while messing around with the code is that for the purposes of upgrading Moonless's bite attack, the game checks how many times Moonless has marked her territory every 40 frames since it is a parallel common event. I think it will be more efficient if instead of doing this, the common event is called up only after there is an incident of Moonless marking her territory. I dunno if it will make much of a difference but hopefully it will help a little.
