Hello! And thank you for the feedback!
We actually have many things in mind. A full day cycle with light changes, traffic, opening os new areas with time progression, an economy system to have variable costs/profits... all sorts of stuff.
I have a mini story in the back of my head too, but it would take a long long way to learn how to implement it!
Regarding th UI... I really don't know, haven't had that issue... it's probably my inability on configuring an responsive UI ... sorry for that!
By the way, you're game is awesome! It bugged out after a few deaths (... a few to be kind to myself...) but I loved playing it and the story is very instresting. I'll try it again to see if I can go past mage stage 2 (too many firaballs on ma face!)
