Great job for your first 3D game!! I really like the mechanic of the game. I couldn't think of why it reminded me of something until I read your description of what inspired the game. You did it justice and made it your own too. There are some interesting bugs here and there but I was still able to enjoy the game to the end. Good job!
It seemed like some of the collectables would keep adding up in the score until I moved away from the original collision location. Some instances did this, some did not. I assumed each collection was only supposed to count once? That might be the only bug I encountered (I forget easily lol. I also played 10 other games at that time. They could've all been running together in my head). Nothing major or game-breaking though.
