Viewing post in Timeshifter jam comments
Yeah I'm not sure what the problem is, when I download it I get a .zip file called "timeshifter-win64.zip" (or -win32.zip for the 32 bit version) and it should contain a folder called "timeshifter" with "Timeshifter.exe" and "Timeshifter.pck" included inside it. I tested this a few ways. Are you sure you're unzipping the file correctly? I've definitely seen at least three people successfully play this on Windows now, and I haven't modified the upload since the official submission day. I don't know why the folder would be empty.
