itch.io

I know this is a foolish question to all unity veterans. How do I open the game in unity with the downloaded material ?

It dosent come with the html file... and when I export it with construct 3 I have to pay a bazillion dollars to do so 

Ok thanks, Can you look at my post in the pixel gun maker you made later

i cant download it 

Is it an html game? does it have an idex.html
