Move your mouse around, if the red laser arms touch the monster, you go to the next backdrop. You have as much time as you like to try and kill the monster.
This game may a bit similar to "How to Create a Shooting Game" in some catagories so thank you to those who have created a shooter game or have a tutorial on "How to Create a Shooter Game". Thank you for sort of inspiring me to create a game similar to this one.
