Tried on website and it worked but I can't download and play it on itch client.
The issue is that the windows build "Resistance is Fruitile 1.666 for Windows" isn't marked correctly in Itch.io, notice the windows icon is missing beside it (but the other builds for other platforms look ok)
@PhasePixel, is this something you can fix easily? I noticed when I was reinstalling some games on a new computer
