the only "update" was uploading the untouched .zip file so people could easily download the game if they prefer. There's no explicit rule against that, as it's still entirely within the realms of the project being worked on within the jam. A few people have done this because it's not against the rules to make slight alterations, or in my case, literally just posting an alternate play method.
Ok well if you could please open up the original file (you can do this by unhiding it in itch history) I will happily play and vote on your game. I don't think it's ok that people should just have to trust the content has remained the same because someone says so. I trust what I see not what people say, and if I file says it was updated two days ago, how am I to know it's just a zip? Yes multiple people have done this and I have not played their game or votes and I have left feedback. I don't mind if it was updated 5-6 days ago as there were extensions. But I draw the line at 2 days ago as that is just way too much time for people to do extra work and it's very unfair for everyone else.
