That sounds really cool, I think you ca do this with your plan.
The mechanics are pretty simple, but I think, it can be truly challenging.
The only thing that will take much time is the polishing. maybe you should plan more time for it. The icy tracks seems to be a crucial part of the game what chooses over the win in the game, if I typed it correctly. You know what I mean, right?^^
But, I think, this can be a challenging, but very fun game. I would play it if it will be finished soon. Subscribed^^
