Hi :)
That's odd I could only imagine that it is a false report. This is also the only report of this kind so far. I downloaded the file again myself and did not get any warning.
I would suggest ignoring the warning, but if you are not comfortable with it I can point you to a compresssed version of my game that someone made on F95. (The quality is minimally lower but the file size is much smaller. Feel stupid that I can't do this myself. ^^')
-> F95 Link
-> Direct Download Link (Workupload)
Hope it works somehow!
