Planetarian is finally available for purchase on Steam!
It will regularly be priced at $9.99, but it is currently on sale for $7.49 until September 19th, or one week!
Hurry and get it on sale while you can! I know I'll definitely be getting it for myself soon, even though I've already read through a fan translation! With no choices and only a few hours of gameplay it's definitely worth a reread. If for some reason you haven't read Planetarian before, I strongly recommend it! But remember tissues of course :3
