The only fangame I've played was Pointless. It's got really good production values, there's clearly a lot of work that went into it, but I just couldn't see it as an extension of the universe, for me it's just a "LISA-like". Despite being really, really, hardcore truly into LISA, I feel no interest in any other fangames. None of them feel like they really "get" Dingaling's vision. Most of them clearly veer too much towards humor, or too much towards edge, while Ding somehow immaculately navigated between the two. Painful to me is a complete, holistic experience that never required any additions.
