It's very short so not much to comment about.
I'm digging the plot so far. You could drop the EYE references unless that's what you are seriously going for because it breaks immersion in the setting right at the start.
Combat is ok, the animations are weird like when I try to retreat I'm getting attacked by the enemy on the way, which is animated by having my team walk up right next to the enemy.
On the merchant screen there's an orange icon on the right that isn't described with text, so I wouldn't have any idea what I'm buying.
The art... Why would you do it to yourself? Making extensive lineart for natural scenery doesn't make sense especially in this case and the result isn't that great. Just grab proper paint brushes. Character art is decent and the assets where lineart is used well (like the vehicle) are great.
The music at the start wasn't very good and it was distracting from the dialogue, but after that it wasn't a problem, as in it either somehow blended in well or was too quiet.
I counted a few typos, though I didn't take notes.
