Hi there! Thank you for your continued interest in the Schlo project. This is an interesting question: I've had to think about how to answer...You're always welcome to leave me a comment on here. I actually don't have any other ways of contact at the moment...
All of the schlo projects are related, though schlo checkers and schlo pink and purple were speculative and most likely didn't really happen. The events in Schlo: Final Stand happen about two years after the events in this most recent project, schlo: confession. They're all from the same timeline! I am planning on covering the Schlo: Final Stand storyline again, but it is taking some time to get to that part...
Preparations for the next release are coming along well. Take care! :)
