The gameplay in The First Day is pretty simple, but is based on very unusual mechanics. For example, it would be worth mentioning that the very concept of top and bottom is blurred in this game — here you will walk on the floor and ceiling, influence gravity, change the rules and laws, and do much more. For example, there is an abyss in front of you, and there is no way to overcome it — you will have to find a portal that allows you to reverse gravity and go over the ceiling, where there are simply no abysses.
