Not Real Contest - Unity FPS Target Practice

The games pretty good as its running smoothly on my age old Core 2 Duo, but theres a lot left to be desired.
1) I cannot figure out how to go to the main menu at all.
2) Grenades should explode on impact
3) There should be a knife animation and the button for it should be customization [such as V or E] and it should be be deadly
4) Theres a wierd glitch where if you shoot an enemy another one at its side will die too.
5) A cleverer AI. I was able to stand beneath the stairs and no one fired at me
Its a good game considering its still in beta but this is what struck me after 5 minutes of gameplay. Best of luck with future projects! :)
