There is now SDL version too, that should work on Linux with minimal changes.
Secondly, I don't like some of the implemented changes - primarily the aiming mechanics, the profile, the square font, a few other small things.
You prefer distorted view? That’s unbelievable to me as if you told me you like to eat sand. But you know that’s just a setting you can change, there is no need to dislike it. Just set it any way you like and feel free to torture your eyes and mind with any kind of terribly skewed and unnatural geometry you wish.
Third, it lags behind the main dev version in changes, which is what I usually use.
I’d say it’s the other way around, that you are behind not only for all the bugs I already fixed, but also for all the new bugs that have been made in the meantime.
Finally, and this is probably the most important bit... a lot of the changes are nice, but ultimately don't change the game that much. I really want things like jumping to play an enjoyable role in the experience, and they... don't. So while I [i]could[/i] use your version, the actual reasons to do so are not terribly strong.
Jumping needs specially designed levels to make use of it’s full potential, but it can be pretty useful in everyday situations too. You can jump over fences or through a window without incurring speed penalty, for example, and sometimes that can make a difference between life and death. Kick/push is even more useful, especially if you are getting surrounded, and then if you use it wisely it can save your life from what was previously inescapable situation. But the best of all I think is new targeting system, it makes the whole game at least 100x more interesting for me, especially with chain-kills. It’s tactical, it requires of you to think and plan in advance, it’s a perfect fit for this game, makes total sense and provides very entertaining challenge. I’d say those are rather huge and important changes, if it wasn’t for the new targeting system I think I would have stopped playing and working on this mod quite some time ago.
