Good take on implementing a 2D game, in this case Pacman, and making it 3D. It shows promise, I would say it needs a little more work. It would of been nice to throw and move at the same time. Perhaps make the collision area for the orbs bigger, otherwise it can be a little tedious missing it ever so slightly and you need to turn back to grab them.
I also thought about a minimap, but that allows you to make the game more challenging to also be a memory game. I'm not going to lie though, genuienly was terried to meet the troll. But thankfully the noise he makes prepared him for me :)
Great job, I hope you're proud of yourself!
