Hi :) Thank you for trying our game, it was for a university project, it was our first experience, so it is still not perfect, because we can't use the pause menu, when we exist the endings we can't use the main menu, and it is not supposed to pass through the doors (in that level you need to pick up only one item, and go the door of the same color and press E to open it and go to the ending). I updated the game so that when we get one of the endings we go to the Main Menu. In the future we plan on making the game working correctly.
Thanks again :)
