I downloaded the app directly from itch.io.
I use Windows 10 and Norton Antivirus. When I tried to open the .exe file after extracting the files in the zip file, it loaded for a long time on my computer. It never opened and it caused my screen to go black and only the cursor and dock was seen. I tried to log out and it would not, I had to manually shut off the computer. When I turned it on again it was extremely slow, Norton Power Eraser did not run correctly and would not close after giving an error. My antivirus was, for the most part, disabled. The virus scans seemed to get stuck on a temp file somewhere.
After giving it a few days, it seems my computer is working as normal. Not sure what happened but my guess is that there was a virus somewhere.
I have the rKill script on my computer somewhere if that would be useful.
