Having all characters help each other escape would be an interesting final twists. Maybe they are all locked up in the same building and they have to find and reach each other. Then the player can switch between characters in-level with a special button press. That would make the final mission also more unique.
I know I have a very irregular release schedule, but I can now work on the game every mid-day. So it's fully part-time. I will aim the next release on two weeks from now, Sunday 23rd. It should have almost all features and levels of the full version. Then if you like, we can do final tweaks before going on steam. I will give you access to the full version as promised ^^
I also wonder if I should keep the free version of the game as a separate game instead of turning it into a demo. Like a free smaller version with its own story and levels without a guild and skills. And a full larger version with the guild and skills and everything.
