There's an inconsiderable amount of lag when you reach to level "Your room?" and carries on when having to reach to a study room having to hit the buttons.
Do you happen to be playing on an external USB drive / Hard drive? I'd recommend you try running Grove on an internal drive (such as placing it on your desktop) as USB struggles to process the rapid image checks.
I do tend to have GROVE on a main drive which is my desktop but something could be fact of performance issues and also the jump pads also causes lag issues when not activated by the altar necklace
