it seems like the game speed is way too fast, at least the animations are, I've seen other footage and it seems to be normal speed, do you know why this is happening or is it just me?
no no, it happens to me too
the problem lies in the RPGmaker engine not having Vsync turn on by default for anyone with monitor that have higher refresh rate than 60, but the game engine don't just make the game run smoother but instead double the speed of frame generation, if you have 144 refresh rate monitor, then the game will generate double the frame and double the speed.
so what you need to do here is to go to your graphic card setting, target the specific game launcher, and limit the frame rate into 60
