itch.io

4 months later, I had the same question. I dug back in the updates and further on the patreon, and there is a version on there that is 1.85. 

As far as I can understand maybe they had messed up the releases or something but the continuation from part one was through there. (link to their patreon so you could find it if not already done - https://www.patreon.com/futabox/about)

Great game, but a honest feedback, and generaly a good practice for any game dev:
In future updates, better put the start ups sound on the system to .5 (50%), the intro was a legitimate jumpscare on full blast.

Rest is great!

Just a tough, if the file size could be an issue, some use MEGA for the files, might be worth checking too as well :)
