Aw shucks, I'd love to try the free version to see if the paid is worth it, but with just a google drive thats always "unavailable at this time" it doesn't look like that'll be happening. :( Would more forks be an option, or do you feel the costs or setup related aren't worth it for the free version?
Thanks for letting me know! I wasn't aware the Google Drive link had become unavailable.
I've now added a new mirror on GoFile, so the free version (v0.32.5a) should be available again. Hopefully that resolves the issue.
I appreciate you taking the time to report it, and I hope you enjoy trying the game! If you run into any other problems with the download, just let me know.
