I'm not sure if this is the right place to put this seeing how it's related to the game's engine not the game play it's self. So sorry if it's in the wrong spot, feel free to tell me. I'll try not to make the same mistake in the future. So this game uses RPG Maker? I'm pretty sure those run on Javascript. Nothing wrong with that, it's just that Javascript is single threaded. Which means it can basically only check one thing at any given time, well without some really really fancy coding. So if you have a lot of things that need checking simultaneously it can cause the game to lag/slow down because of the constant switching of threads. It might even possibly cause bugs. I think this game is a long way off of that but this is more of a future warning I guess? If anyone with more knowledge on the subject feel free to tell me I'm dumb and/or correct me.
