This is probably my personal favourite this time around. I think it's the only one that ticks all the boxes: is "so bad it's good", is retro, and is something I liked. There are other games that do some of the above (and some better than this) but I think this one is the best for "all of the above" if that makes any sense.
It really captures the feel of an N64 game, maybe more an iffy third-party title than a solid first-party one, but it gets it right even in a lot of the details. Often it looks horrible because of it- the text in particular is atrocious- but it looks right.
The story and dialogue is weird, but funny. Same goes for the odd-looking character models. I like that there were many shout-outs to various games, some more subtle than others, but it didn't rely too much on parodying one in particular.
The gameplay is just okay, and that's not something I really realized until I'd thought about it for a while because it gets so far on style alone.
My only other gripe is that it's lacking quality-of-life features like pause, save, and skip dialogue, but the game isn't long or frustrating enough for it to really be an issue. Oh, and quads were really the Saturn's thing, not the N64's, but that's ridiculously nitpicky even for me.
I don't know if this is, objectively, the best game in the jam. It probably isn't. But it meshes the most for me.
