This is a brilliant game!
Very well designed.
The very best game coming from Gila in my opinion!
10/10 and highly recommended!

And where can I find LUMEN 2.0 framework? I can see only the old one.

Thank you very much!

The LUMEN 2.0 framework hasn't been formally written up yet. I'm still working on it as I make these games using it, until I feel like I have a good grasp on what I want it to be.
