I uninstalled Signalis after what I THOUGHT was the ending but if you’ve played it then, well, you know. Had to reinstall it after learning the truth online, and then I got mad and deleted it again because I was fed up at that point. Kudos to the game for doing that though, never seen that happen before.
The bloat, plot changes and design choices for Rebith put me off for a long time. I’m playing it now and trying to judge on its own merits. I am enjoying it, though I still stand by my criticisms. The Mythril Mines for instance, was three/four screens in the OG, in Rebirth it’s an hour and two boss fights.
Ah yeah. I have vague memories of that ending and think I almost did the same thing - though probably looked it up immediately and kept playing through

Can't speak about Rebirth but you're opinion is one I've heard a lot. Seems that people love or hate the bloat with very little in between!
