Hey Vtran!
Thank you for your lovely comments, I'm very happy to know that Kokorogawari has caught your interest!
We would definitely recommend anyone to get the deluxe version as it contains the artbook of the artists' CGs and unreleased sketches, the beautiful soundtrack painstakingly composed by our artists and of course, the secret SS stories! :D
If it helps however, we are currently having a Greenlight on Steam to help us get onto the Steam store. There will be download packs (of course, more expensive) that one can purchase at any time. So please think about which platform you would prefer buying from!
In the meantime, please help to vote for Kokorogawari on Steam!! :D
