I’ve give the game/experience a test and I think it will would an amazing game but I notice a couple problems.
The teleportation is very slow, and it’s hard to understand what the buttons will do. I suggest adding a short description below the buttons so players will understand what it will do.
The UI is very simple, I suggest adding some textures to more it look more appealing and interesting.
Your game will be very popular in the future and possibly might be a alternative for teachers to create fun quizzes for their students.
