Thanks! :)
It's a good idea. If I get to make a sequel or update for this game, I will definitely add destructible obstacles in some form.
So, considering that this is the second open world request (huge feedback for me btw), I will start developing it as an update for High On Track as soon as I finish with a small update for my other game.
I do not know how long it will take me and I do not promise that the world will be any big, but I think it will turn out to be a fun new game mode.
Follow me, I will create posts about the development process :)
