Thanks so much fan! I don't have any plans to stop posting on itch anytime soon, luckily :D
It's not the last in the series, but I have no plans to stop making these any time soon since they're a lot of fun, so if you're interested I suggest just getting into it. They're all semi self-contained stories (they feature characters from previous games but the conflict is tied up at the end of each one, so you won't be left with any cliffhangers).
