Nice, relaxing little game. You shoot a colored ball from the launcher on top, and that ball breaks loose all the color matched objects standing, hanging, or railroading around. Those free objects can break loose yet more in the same color, but it all eventually bounces and slides down to your catch bucket at the bottom, which you mouse side to side to catch all the goodies. A shot that doesn't break loose any field pieces resets your bonus multiplier, this seems to be the only obstacle the game puts against you. Keeping the big points rolling will take bank shots, timed sniping, and a little planning to keep your options open.
The graphics are clean and simple, and the animation runs perfectly on my Intel MacBook (integrated graphics). Controls are simple, point and click with the guidance of a ballistic line. The game has relaxing music, standard fare for any puzzler.
There are no enemies, crucial obstacles, or game over screens in Spring Up. To some, this might sound pointless, but I was caught for the full length of the demo.
