Ninja Roll 2 is a simple ball rolling game that has you drawing a line for your "ninja ball" to roll and bounce down. The goal of the game is to collect all of the stars on each level.

The game has a very sparse look, and the physics of the ball remind me of the superballs that I played with as a kid. It's actually frustrating how bouncy this ball is. Sometimes it's hard to maintain momentum because just as your ball is about to ascend a ramp, it hits some tiny bump and bounces off in an unexpected direction. To be fair, part of the fun of playing Ninja Roll 2 is watching the ball make crazy moves.

Some of the levels appear physically impossible at first, but that's where your ball's incredible bounciness becomes an advantage - you can make it perform moves that you would have never thought possible.

My only gripe with the game is that for some reason it was choppy to the point of almost being unplayable when running in Firefox, but in Safari it is perfectly smooth.

There's a certain style of time waster that I find incredibly addicting - those in the "see how far it can fly" genre. Two previous favorites include Shopping Cart Hero, and Air Voltare. If you like those games, you're going to love today's Time Waster, Learn to Fly.

In Learn to Fly, you play the part of a penguin who is not happy to be a flightless bird. Your job is to research the best way to achieve flight, which in this case involves sliding down a ramp and flying through the air with a glider strapped to your back and rockets strapped to your sides.

There are 4 increasingly harder levels to master in Learn to Fly, but as you go you can purchase power-ups for your equipment and your abilities. To beat each level, you must exceed set goals for height, distance traveled, length of flight, and top speed. To win the game you must travel at least 6000 feet, and you then receive a rating based on how many "days" (test flights) it takes you to get there. It took me 25 days to achieve flight.

I have to say, this sort of time waster often does not have an end goal, but rather continues on ad infinitum. It's nice to know that once you hit the 6000 foot mark, you've won the game. How many days will it take you to achieve flight?
