I picked that game up but haven't had time to play it yet.
I beat Lumini yesterday, enjoyed it
It's great, highly suggest it.
Fully completed Thomas Was Alone. Charming little platformer that has some great narration and takes around 3-4 hours to 100%.
Also recently completed Analogue: A Hate Story. It starts out pretty slow, but then it gets pretty dark. I mean, while Hatoful Boyfriend took a while to get dark, Analogue isn't really afraid to dive into it once you get into some of the meatier texts. The soundtrack is pretty great and the writing is fantastic I think. I'd highly suggest picking it up on sale along with the soundtrack, especially since you can 100% it in around 3-4 hours.
