I don't know, I was asking just in case.
The only way would be to print it, play it with some people etc.
Or maybe what I could do besides improving the game is digitalizing it in tabletop simulator or something like that.
I think that's a good idea. All the traditional games are going digital. If not you can still post your game and see if the community will be able to give you feed back. But you need to have a page for the game for them to provide feedback to you, if they decide to setup and play your table top game.
