You been doing some fine work in these last few games, really hard to say anything negative...

Of course there's some things that could be improved... I mean, that instant crouch is horrible lol. xD

Adding several buttons is also quite... Confusing, even more when the text switch so much between auto and manual... There's a nice chance people can skip the text by accident... Unless you added a delay.

Overall it's a great game, quite confusing design choices in these that I mentioned though. ;p
