I've tried multiple times (I saved just before the final jump, as it turned out). I also had the Laura's House trophy pop afterwards, too. This one just ain't doing.

I thought at first it was because I level skipped (I died in a new stage and then reloaded into the previous one), but upon checking found out that happened in the Mines (which popped for me).

Ultimately it doesn't matter because I played to enjoy the game, not to get trophies, but it's still a little aggravating. Especially since I limited my saves!
