What is monvernt?
It's a multidirectional shooter as well as a very, very, VERY horrible misspelling of "movement".
You're a thief who managed to escape from prison, and all you have is your trusty gun, which can shoot bullets either rapidly or normally. There are no ammo crates (for now) and you have only a limited amount of bullets, but thousands of police (which keep on coming!)
Survival mode: Move your mouse to set the angle to shoot, then click to shoot. If you're using rapidfire mode (A) then hold down the left mouse button to continue shooting. Press (D) to switch to normal mode. You'll have to reload your ammo every time you shoot in normal mode, and if you're using normal mode you need to click once, then release the mouse, click again to shoot, release, click again to shoot, etc. Stay away from the police -- they lower your health! Your speed is also proportional to your health, and it takes a lot more energy to fire a long string of bullets in succession. See how long you can survive!
