So, just picked this game up and playing it through with my g/f. We are loving it so far; I think it's easily Arcen's best game since AI War.
However, we did have some trouble initially getting the controls set up. Why are there two gamepad control slots for each key? Also, the bottom one does not seem to respond well to attempts to change it - if I click on it at all it changes to say something like Axis #5 (Neg) and then won't change to anything else or let me clear it. I ended up having to go into the config file and manually remove the second line of gamepad controls from everything.
Also, just a quick suggestion: Near the beginning when you are separated by the broken bridge, the game does not make it clear that you are supposed to stay separated. I lost a few points of health trying to find a way back across the bridge before I realized it was futile - this is espeically true because Lela has a line about repairing the bridge quickly so you can get back across, but there's no dialog to indicate that it's impossible.
