This is my first time trying the demo but I was aware of some of the lore coming in. Obviously a lot of effort was spent making all of those background and story sequences. The EYE: Divine Cybermancy references lead me to believe the ESL spelling is intended, but anyone who isn't familiar with that game will think you outsourced the writing to India so you should probably fix that. Read a book in English when you have the time.
The setting seems pretty interesting at a glance and having characters from different backgrounds who are clearly at odds with each other from the get go was a good idea to organically introduce lore about the factions into conversations. Reminds me of the Morrowind Tribunal/Ashlander Dunmer dynamic.
I appreciate that you are trying to do something different with the combat with the lanes and all but sadly and, as others have pointed out already, the tutorial is broken and layered on top of a dialogue sequence. That's probably the most pressing issue with the game right now. After a couple of encounters I got the gist of it, but the full demo so far had like 4 fights in total.
Another issue is the UI in general. Some textures are layered on top of UI elements or don't disappear when you close menus and such leading to buttons not picking up mouse inputs. Buttons outside of dialogue sequences lack feedback when pressed too.
Furthermore, the text and icons are just far too small. Unless you are planning on having 20 vs 20 fights I think you can afford to make them a little bigger and increase the default zoom.
That is all I had to say, the setting looks interesting, but the game portion could do with a little more polish. Good work so far.
