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.
