The cutscene happens before you get the GameJolt trophy. Aaaand it softlocks you, corrupting your ENTIRE save-game.

So, when I unlocked the cutscene, it didn't play so I thought about opening another window for the game. Then I opened a second window of the game, closed it then proceeded on the main one, with the cutscene playing "normally".

If you do what I did and wait until the cutscene ends, your save-game gets corrupted, and you have replay the game from the beginning again until you reach your old progress. While hopefully getting the trophy on GameJolt before that happens.

But if you have a backup save-game that was saved right before you attempted to unlock the cutscene, which I did this time since Ray warned us about it, you can get the GameJolt trophy without losing major progress!

Even though on the backup save-game it doesn't appear in-game on the trophies menu...
