EDIT: SOLVED! Was able to download through Firefox. The itch.io app still doesnt work for this game specifically. Since the dev may have abandoned this game it might stay like that.

So,

I bought your game today because it looked fun and all. So far so good, itch.io prompted me to download and install the files I just unlocked with my purchase. The installation failed though. After that when I try/tried to install the game there are no files to select and therefore nothing can actually be installed. 

Any tips on what I can do?

Sorry about the bad screencap. When I wanna extend the install prompt nothing comes up. 

Edit: Got an actual error this time
