So I think I found a game that's breaking the rules of the Jam.
Mainly, this one uses actual Sonic sprites, actual Sonic songs, and as a result is not only not a proper demake to the best of my knowledge (going against the spirit of the Jam) but also goes against rules that have been clarified/established in other discussions (mainly, no copyrighted content): https://itch.io/jam/demake-jam/rate/296881
So uh, what exactly is going to be done about it, if anything...? Does it even really break the rules, or just guidelines/things that are highly recommended to be done/etc...?
P.S. Creator of the game, if you're reading this: I have nothing against you or your game, the game seems to actually be a pretty neat idea, but rules are rules, even if they admittedly weren't explained perfectly, and I couldn't find any non-public communication options for discussing it.
CONTINUED: As I was writing this post, I think I found a few more iffy games that miiight potentially break the rules too. They're not quite as concretely in the "it breaks the rules" zone, but I'll still note them in the chance they are:
Wyvern's Crest, which if the screenshots are anything to go by, it might be on the border of NSFW, though admittedly it partially depends on how you define it (e.g. do you define it as 18+, which this very much isn't, or do you define it as something that might get you in trouble if you looked at it at work, which this possibly could be depending on who you ask): https://itch.io/jam/demake-jam/rate/296931
Ghost Story, which... doesn't appear to be a demake of anything in particular? The only thing that hints at it at all is the mario-64 tag, and uh... the graphics certainly aren't a downgrade from Mario 64's graphics if that's what it's supposed to be a demake of. In essence, it's not really a demake from what I can tell? I could be mistaken on that, and if so, feel free to point out what it's actually a demake of, but best as I can tell this at least doesn't go by the spirit of the Game Jam, even if it may not technically break any concrete rules: https://snarf.itch.io/ghost-story
P.S. I have nothing against the makers of these other games or the games themselves either, your games seem to be pretty neat too, at least for how much progress was made on them (particularly in the case of Wyvern's Crest, which was apparently rather unfinished), but once again I question if they followed the rules of the Jam.
