Thanks G. I found out, the grandma is not unlockable yet as far as I know. The dev is still working on content, I assume there's more if you cough up $9 because that will get you the early access version as opposed to public release. Again, I appreciate the help.
You're welcome, my friend. I hope I've helped. By the way, do you happen to know how to continue progressing with "WRIC"? I feel like I'm not making any progress even though I have 100% of its stats (except for lust)...
