Thanks for playing!
I´ll check the control scheme, the reason it is really weird is because I test the game with a controller and I haven´t really thought about the keyboard controls. I rushed too much to finish the demo, that´s why I could not finish the use of guns, to use them in this demo you need to aim before shooting. I´ll check the damage of the things for the next version, to make that things that are stopped can´t damage the player.
