Green flag twice (for it to work properly), WASD to move and the rest is explained in-game.
-storyline- in DTB, you play as Scratchy the cat. At the beach it is hard for Scratchy to relax, as others are playing ball games and the balls are hitting scratchy regularly. There happens to be someone who throws ice cream at you frequently (how he/she stores all of it, I don't know) and the ice cream replenishes health (which you lose by getting hit by balls), so go and dodge your way to victory! -UPDATE LOG- 1.0.4 Improved the balls' moving mechanism 1.0.3 Fixed win sequence 1.0.2 Changed a few things 1.0.1 Added an Easter egg
