itch.io

My Game will not work, Not matter how many times I re-download it it still will not work, I cannot get it to work on the itch.io App and from my browser, Is there something I might be doing wrong or does it just not work for my Laptop? Or do I need to re-download it on steam if so will I need to pay for It again? 

Edit: I bought the game on steam and It wont run either? I have no clue what I'm doing wrong.

So, I've payed for the game and downloaded it, But the game always crashes, I open it and its shows a black screen then just shuts down. I've even re downloaded the game multiple times, But yet I get no where.
