I made Angular Project with BabylonJS Framework and Havok Physics.
(For curious developers)
Demo Project Here
https://ajna4taiga.tk/PushBall/index.html
You zoom in/out camera with scroll on mouse. Camera always look at Ball.
You push Ball with WSAD.
You can explore mazes and physics (Havok - nice physics plugin)
NIce exploring 
no. it is button to open barrier. And you should go around.
I should put there finish. This is just demo of concept.
Aw this brings back memories: I have got balls or Hamsterball . Super addictive gameplay.
Please keep working on it!
No money no funny.
Low money low funny.
No time no funny.
No team.
So things go slow.
Another maze idea for your game. The cube should have a gravitation force.
You can start doing it.
challenge accepted. i will create a labyinth on a sphere and let fish swim in it.
Great. Interesting journey.
Good and interesting Book you give a reference/link.
