Thank you so much for the feedback! Yeah we wanted to have them to create a separate feeling of scenes, but yeah maybe it would have worked better without blank screens.
The texts were actually inside the triggers, so if you stayed inside the collider or looked at the certain object it shouldn't disappear.
Hahah, yeah we though that as well, that is why we hinted the player to the main gate, but we didn't want to add running, since that would kind of break the immersion of stealth.
