Ok, first of all, great game.
It's rare to find such a game for free, for linux.
It worked pretty fine from the start, no tweaking, no missing libs or any other technical problem.
Then.
I've NEVER played any UFO/X-COM games, and i found the interface not really intuitive and a bit unconfortable: it wasn't easy to figure out the rules of the game.
In detail, I won't expect to go to the "aircraft" menu to change the equipement of my squad, and I'd find useful to be able to buy things right from the equipement menu, or at least close to it.
The tutorial is completely useless, as it simply states the name of the interface items, which can be found in the interface itself.
A useful device, would be to assign the right mouse button (or SHIFT+left or something else) to the description of the button/interface element.
For example, in the Reaction button, what's the difference between one and two marks? Why my men don't always react?
I know no rules other than the real world, so i expect that if an enemy appears right in front of the barrell, the actor should be able to react.
It would also be great to have, in the uppermost tab of the tactical screen, the faces of the team members instead of the numbers, even if it would be quite bigger.
I was also a bit confused by the recruit/hire menu: it wasn't straightforward to discern between hired and not-hired personnel, the x/v button was just a flag, one (I) would expect hiring someone a bit more "definitive" procedure.
Like: hired on the left side of the screen, available for hire on the right.
Not sure if a comment on the game system/balance is appropriate, but i cannot understand how do i earn money other than pillaging alien weapons: the research and production of my base is staggering slow, but i cannot afford other labs.
About the learning process, I'd like to see a learning rule based on failures: whenever the success probability is at least say 20% and the actor fails, she/he's awarded a very slight increase.
This would allow the actor to improve all his/her skills with a peaked preference for the one/two that are more used in a non-trivial way (like shooting always point-blank or whatever).
If applayable skills may be influenced, the actor may improve also when wounded.
Last thing: the "register" button on the forum is almost impossible to see, it took me like 10 minutes to find it. =)
Hey, i've been critical only because i liked the game and considered worth using my time to write here.
Is an overall impressive job, with great graphics and gameplay.
Keep up the great work!
