Tell me about it... My game had a spelling error in one of the levels where it said "obious" instead of obvious... so I opened it up, corrected it, build, zipped and exported again and when I checked the next day... it said "obivous" - because checking things is hard and reuploads are so much fun.
You could add the hint to the game-page-description. That doesn't count to the 3 hours in this jam and rocknightstudios usually reads that on stream.
