I don't know if I'm in a position to give this a rating, I looked through the comments and found that space and f are the controls, but I still don't know how to start, I wasn't able to get to the start button and neither the help or start text did anything. I'm really sorry if there was a solution to this but I could only really assume that f was some sort of attack?
I also tried to download the windows file but it was missing the exe and i don't have a mac vm so I can't really try it there.
All I can really say is it's a good idea to add controls to the description and with puzzle games like this adding a hint or something to get started would be good especially if you know its hard.
