i'm kind of interested in this, but also nervous because i don't know if mine will hold up well
are there any requirements the game has to meet or can it just be like. a silly little game?
There's no limit on silliness, seriousness, scope, scale, size, tone, type, or tempo. Your goals are your own, this is just a space to share and be awesome along other awesome people trying to achieve little goals of their own. Many of my favorite games are squarely within the genre of "silly little." I, personally, would welcome such a contribution here!
Of course, if this gives you more anxiety than enjoyability, please don't feel any pressure to participate.
