I always somehow end up on art videos that go from a painting down into another painting and so on. Happy to try it out as a game :D. I did like that not only the rooms were scaling up and down but some of the objects inside did as well. No idea how you managed to finish all that within 48 but well done.
PS my brain was in a bit of pain when i had to pickup a weapon, knowing that i have to press "E" but the "W" suggestion tricked me every time.
