I’m going with three stars because I played for free on a random whim and knew nothing about it going in.
The whole point really is the story/overarching theme, (both of which are good, not extremely creative, but good).
The gameplay itself…fairly lackluster. I consider a game good if I’d play it through more than once. Omori doesn’t have much replay value, even with it’s multiple endings…it goes on much too long to get to them IMO. If I’d paid for/waited on Omori, I think I’d be pretty disappointed with it.
