Description：You are an alien in a weird disguise on an earthling-kidnapping spree.\ \ \ \ Collect as many earthlings as you can! Giant robots, exploding cows, superheroes and psychic toasters? This game has got 'em all!\ \ \ \ The narrative kicks in after you are familiar with the game mechanics and events will begin to occur in real-time. Survive till the end to unlock the bonus!

Instructions：Fire gravitational projectiles into enemy units.\ \ Make sure you don\â\€\™t let too many units through and don\â\€\™t allow your canon to be destroyed.\ \ \ \ Use the mouse to fire the canon. Click the centre and drag it back to set the direction and power.\ \ The more power you give to a shot, the more unstable it will be. Instability will add a chance of the mortar exploding before it is fired, causing damage to the canon.\ \ \ \ Enemy units will bounce back or explode when they are hit.\ \ Having them bounce against other units will do further damage.\ \ \ \ You will receive skill points as you level up. Use these to upgrade your gun, or invest in special abilities.
