hi, does anyone know why it says server sent GOAWAY and closed the connection?

I'm having this exact same issue, were you able to resolve it?

I'm having this issue too. I also tried downloading the game through several different browsers (Firefox, Edge, Internet explorer, Waterfox, and Chrome), none of which have worked. 

Me too. I did what IAmTheGeek did multiple times but nothing worked :/ Tried downloading it on the itch.io app but same issue there too.

Late but same. I downloaded it, but when I tried to open it it says "application can't be opened".
