As far as I can tell the download should still be working. Unless you're referring to trying to download a non windows version? If that's the case unfortunately we weren't able to get an alternate version functioning in time.
Theoretically our game *should* be able to be converted to browsing as the only real button is left click and ESC to open the menu. It's something we'd like to be able to try making possible, we just didn't have time. We tried exporting as a browser version but it had issues so we just went with an .exe for the jam.
