Hooray! I found the baby!
This is a platformer, essentially: jump over things on the floor, avoid things falling from the ceiling. It took me a little while to work out how to avoid the falling chandeliers, or more importantly how to trigger them to fall without having them fall on me, and I think the collision hitboxes for the holes on the floor which kill you are quite harsh! But the game was fun enough to play -- there doesn't seem to be a consistent set of rooms to navigate around (so you can enter a room from the left but then not leave that way) which suggests that perhaps room generation is procedural and random? This isn't necessarily a problem, once you expect it; the only time it becomes an issue is where I realise that I missed a healing bottle and try to go back to get it and can't :-) So, a simple but effective game!
