I am very interested in the game, and I can't find a way to get that version. Is it even obtainable?

the three version are avaiable on game jolt (https://gamejolt.com/games/dogurai/31943) and maybe will be avaiable on steam in time (since it says soon on the page)

Im starting to think the dev stopped working on the game.

Edit: Wow the game is out on steam since 27 May, 2019 have to get me some new runs soon.
