Get Smashin' and Hammer in your victory!!!!!

Control your character with the mouse and use space bar or the left click of the mouse to smash your enemies with your hammer. You can move faster and hit harder by pressing W or using the right click of the mouse while sprinting.

Show no mercy to those worms but watch out for worms bigger than you.

Don't forget to collect pieces to have a bigger hammer!
