Honestly, this.I think it's time to move on and make new stuff, personally.
While I would love to improve my work, make each episode more distinct from the original episode it modifies, make the story more cohesive, improve the graphics and level design, etc, all of that is really only because it's personal to me and I'd like my work to be a reflection of what I think is great now vs what I thought was good enough then. Sadly that's only wishful thinking for me at this point
I think anyone else looking to revise these should honestly consider just making their own uTUIT.
