I try and visit games about once a year or so. Too frequently and there's not much meat on the bone from updates. If there's been no update in a year? Yeah, that's too long.
I feel like the author's sense of humor is part of it too. You're either going to vibe with it and find it charming, or it's going to annoy the hell out of you. Luckily I'm the in former camp, but I can see not everyone liking it.
