The Mega Link is indeed down. Please consider a reupload. Maybe with mirrors on GDrive or somewhere else?
I didn't look too much into newer versions of the game but if somebody were to get their hands on a newer version or some Gold version I'd be much obliged.
The dev posts on the Gamejolt webpage are rather old. In fact the posts there are more than a year old so I wonder if there even is a newer version.
Thank you.
Edit:
Okay, I looked up their patreon, found out about new releases at the beginning of 2018 and invested a couple of days researching alternative downloads which do not require me to pay. It did not go very well. I only found dead links and fake downloads.
Current release verions are
Gold Edition v1.0.1 (30$ patreon reward)
Regular Edition v2.4.4 (10$ patreon reward)
