Hi, I don't currently have any plans to compile all the games into a single release. There is currently one final release planned in the series, which I expect to be out in a couple of weeks. After that I'm not sure where the series will go.
A collection of all 5 games is definitely on the to-do list. At the moment it's a case of working out what that should look like. I also want to write advice for running the game and for combining the different games.
It's important to me that anyone who already owns the separate releases shouldn't have to pay again for a collection, so I need to figure out the best way to make that possible first.
