What an impressive demo! This shows much promise.
Some minor notes.
It would be nice if objectives were marked completed in Notes when done.
Also, how was I supposed to know which way to take to complete the save the General objective? I chose the path that went to the villain and missed on that side objective.
A dedicated healing button would be nice.
There is no reason to highlight non-interactable items in the HUD like keyboards etc. It just clutters the view and makes it harder to see what you actually can interact with.
