Hi, Fire Frog. As you can see in both of Diguifi Studios' TRS Game Jams YouTube Videos, he's ranking each game as he plays. From what I know of itch.io ratings, the Host must set the judging criteria, so if DS set it to only himself (and maybe Andre) to judge, then no-one else can.
Personally, I'm just fine with not being able to rate others' itch.io games, as it feels like it takes away from the ones who made those games, and it would cause real CHAOS if everyone got to rate games that others made! So it's best that ONLY Hosts can judge. :)
Also, I'll consider your advice about making a Public TRS Games Collection on itch.io, since this thread I made of a TRS Games List can easily get over-run with comments (since I left that option enabled), so it sounds like a better idea.
I'll probably still keep this list updated just the same, as long as it doesn't get too many comments.
As for MY Games, they're all WIPs (Works-In-Progress) or POC (Proofs Of Concept). I've made only a very few myself, ranging from OHRRPGCE, Bitsy, WhimTale, etc, but I only ever uploaded peb's nswe Engine files because he vanished from the internet recently.
I've recently been thinking of making a full game, but I'll see how things go. If I ever make a full one and choose to upload it, it'll probably be a TRS one, since I like the features the engine has to offer.
