Watched the video... Felt good to watch someone play the game and give feedback in real time. I realise now that I should have told the player how to sprint, as it's crucial to get one of the endings.
The two endings you missed were (SPOILERS)
Using the plane while the window was still closed
Sprint-jumping from the desk to the backpack in the wardrobe and using it
Thanks for taking the time to showcase my game!
