Is it worth if I got spoiled

!Major Spoilers!

So I was researching if the game is for me, and got massivly spoiled on whats happening to mari, I dont know the reason tho on why Omori did it. I also spoiler myself with that when the game came out and some clip was shown on my for you page. Be real, do you think the game is still worth to play? I think alot of things in the game came from not knowing whats goind on and what world this plays in. Iam not sure but I probably think Omori is depressed / traumatized by the events and it all plays in his had (or mostly). The game is realtivly cheap, but still I dont want to buy something I regret.
