This is one of the best ones in the jam. If I were to change anything it would be to make it so that the longer a run lasts, the harder it is to keep the demons happy, like the game should get a lot harder later on. Maybe, when the run is going for a long time, make it so that your food and drink items aren't as effective as they are at the start, any mistake makes the demons a lot angrier, and the elevator moves faster.
I'd also add the thing CheesyBoyBen suggested.
This is an amazing entry already, but those things would elevate (haha get it) this to perfection
