The Platform is such an astonishing movie! No doubt that it is a successful Spanish psychological horror. The participants are placed in a certain floor or cell which food is delivered via platform vertically. So basically, the higher floor you're in, the better food you have since lower levels can only eat what those above floors leave. The participants are being switched floors every 30 days.

How many levels are there in the building? To what extent can a person do to be able to survive?

The Platform is available on Netflix, highly recommended! 10/10
