Red Ball 4 is a challenging physics game about a cartoon ball rolling through an idyllic world. The game combines platforming, problem-solving, and momentum in order to create an incredible experience that's simple to learn and difficult to master.In Red Ball 4, you play as a red ball in a 2d platformer-style environment. The world is populated with ramps, hills, enemies, and platforms that you get to navigate as you progress towards the end of the level, Mario style. In most levels your goal is to roll from left to right, navigating your way past obstacles until you reach the end of the level.Just like in classic platformers (like Mario), Red Ball features the ability to move left or right, the ability to jump, and not much else. You can defeat enemies by carefully jumping on them from a vulnerable angle, causing them to play a cute animation and disappear. There are also pickups in the form of stars and checkpoints that look like red flags that you can collect. Stars give you progress towards a bar that fills up as you complete the level, while checkpoints give you a safe place to respawn at if you fall off a ledge, drown in water, or suffer defeat at the hands of an enemy.Red Ball 4 sets itself apart from the competition through its creative use of physics. As a ball, you conserve a huge amount of momentum as you roll around each level. Many puzzles require you to go back through the level to pick up speed before jumping over an obstacle or slamming into an object. Speaking of objects. the majority of the puzzles in Red Ball 4 utilize simple boxes, planks, and other basic things that are simply rendered faithfully in the game's physics engine. In order to get up tall ledges or traverse gaps, you'll have to use your ball to push these objects around into better positions and then use them as launchpads or bridges to get to your destination.The cartoonish graphics of Red Ball 4 add to the game's charm. Levels are clear, brightly lit (for the most part), and are fil
