On the one hand, "leave yourself behind as a platform" is, apologies, not the most original mechanic. On the other, though, the level design of bridging spaces, moving straight up, and handling moving platforms do bring something fresh to the genre.
But there's one thing it needs, and that's a reset button that removes all your past selves. If you're thinking "But no one could play this game so badly that they'd leave a practical wall of bodies that they can't progress past": hi there, it's me.
EDIT: OK, I made it to the end, but just to give you a sense of how bad it was, this is me and I swear I wasn't trying to see how badly I could block myself out.
