Salam brothers!
Tried the game demo yesterday, and have a couple of comments.
1. It has crashed in the beginning of some turn, without creating and dump or log file, so have no idea what's happened. Started it once again - everything was fine, successfully killed all aliens - and then game automatically closed, without getting me into main menu, not sure if this was a correct behavior.
2. During the fight I opened main menu, just to check if there is something interesting. And the problem was - Escape button didn't work there, to go out I had to click something with my mouse instead.
3. Graphics looks better then in Xenonauts 1, but I would suggest to have more rework in arts and sounds. It looks like they are mostly taken from the first part, but I expect to have some new experience in this new game.
4. It would be good to be able to zoom, soldiers were quite small on my screen.
5. Backpack didn't work, not sure if that was the plan for demo to turn it off, or some problem.
