It doesn't really come as a surprise to know that the designer of Puzzle Dimension co-founded the development team of Kula World for the PlayStation.
The game play is very much like Kula World's. You navigate a ball around various stages picking up things (flowers, in this game's case) in order to move to the next level.
The levels are all quite smartly made, introducing new concepts and obstacles as you progress through the game in a timely manner. Being able to roll around on more than just the top of some levels is another neat feature from Kula World.
Overall, Puzzle Dimension is one of those nicer puzzle games on the market. Nothing overwhelmingly difficult, but provides enough challenge (and a decent aesthetic for an indie game) to make you feel good about yourself after beating a few levels.
It's definitely worth getting for the price of £1.99, especially if you enjoyed Kula World.
