V1.4: Intro cutscene + new voice + story reboot

Intro cutscene

Since this was a game jam game, we felt we were missing a little more of background when you start the game.

Therefore, we added a cutscene where you arrive at the bunker where the puzzle takes place:

This was the first cutscene we'd ever made, so it took quite a while to figure out both how to record it and how to work with the environment!

New character voice + story

We wanted to lay a good foundation for the game and therefore the main character is now Vincent Winters and the game takes place in England.
