The Steam page describes it as
Tiny Life is a fun simulation game that aims to capture the essence of games like The Sims series, but in an isometric pixelart style.
In the game, you control a set of people that live together in a household. You take care of their daily needs, build their skills, forge new relationships... or just mess up their entire life in whatever way you can think of!
It's currently on sale but from the looks of the reviews it's still pretty far in early access and missing some components you would expect in a Sims-style game.
I'm curious if anyone has given it a go and what they thought
After seeing this post, I will certainly try the demo this weekend.
