Oh dear, that does sound like a bit of a glitch indeed. That might actually be an oversight on my part (I didn't test the final stretch of the 'evil' route quite as well as I should. I'll definitely look into that!
As for a sequel, I want to do that (And I also want to remake this one in a better engine with more content and better graphics) but I simply don't have the time or budget for it anymore. If the ever changes in the future. Perhaps!
