Hi, I was not able to verify your purchase.
I will need your email to check if you bought the game and also to send you the lastest version.
On Steam the game is not available for Mac, but the one I'll send you in case you bought the game here does.
Please send me an email with the email you used to buy the game to nachos.videogames@gmail.com with an screenshot of your comment so I can verify it is you and to check if your email is in the buyers data.
And yes, you will be able to play the remake with the version I will send you.
