Pretty interesting idea. But I do have a few things to say about the game. First, the dice feels a little bit slow. This might not be a thing you can control though since another comment stated you used openGL and I'm unaware on how openGL works. Another thing is a bug I found. For some reason, when I lost a game and I played another (if it helps, the game I lost I had 0 cash), the collisions for the platforms I placed previously were still present (I say only collisions since I couldn't see the actual platforms).
Other than that though, pretty basic game that could be better.
