Here are some new stuff and change.
Added music in menu.
Added sfx when click in menu.
Added escape key to return to the menu and exit the game.
Added confirmation for exiting the game.
Added effects yellow in Kill them All mode when you hit a monster.
Added some achievements.
This patch will inaugurate the full release, i will love continue doing much more stuff for the game but that take a lot of time and the game don't work as well i tought in financial aspects so its unlikely that i will do other update, but if i do it will probaly be minor stuff.
