So far the PSP library has been made up of two distinct types of games: original content and watered down PS1/PS2 sequels, spin-offs, or ports. While development teams love making original content, with so many systems and handhelds currently on the market, not every studio has the manpower or time for creating an original product. So much of what has appeared on PSP has been made up of low budget porting. Still, games like My My Katamari Damacy shows that there doesn't necessarily have to be this drop in quality when going from the PS2 to PSP, and rather that it just takes some effort and smart planning.

When talking about the latest Katamari PSP title the best praise that one can give, is that when rolling around the world picking up entire cities with the prince's ball, the experience is just as good as the PS2 games. Sure small changes have been made in order to get it running on the PSP (such as tiny objects disappearing as you get larger and a brief mid-level loading screen after reaching a certain height) but in the heat of the moment, the game really looks just like the PS2 games. In addition the game has excellent picture quality (no jaggies in sight), which nicely compliments its large colorful environments.

The audio side, which has always been a high point for the series, suffers from no loss of quality as well. While it's true that a large portion of the soundtrack is taken from first two games, there are still plenty of brilliant original tracks, as one would expect from Katamari music.

The levels in the title are well made with interesting locations and lots of people/objects to roll over. As the player progresses through the game they will encounter the same stages again and again, but at different times of the day and seasons. On one hand it's nice because a frozen ice lake does feel quite different than a summer beach. But on the other hand, it means that there just isn't that many total locations, so players will learn the layout of each area fairly quickly.

If one aspect of the game is likely to receive criticism, it'll be with the controls. Since Kamatari Damacy is a concept based around dual-analogue usage, getting the experience to the single analogue PSP required some changes. On the PSP, the title still plays as if the player is using two sticks. The game assigns the left stick to the d-pad and the right stick to the face buttons. In addition the L/R buttons curve left/right and tapping left+O twice in a row flips the character around 180 degrees. At first the controls feel strange and unfamiliar, but luckily most players should adapt quickly. Still, even after one gets the hang of the controls, the game never feels quite as comfortable as the PS2 titles and playing for extended (20 mins or more) periods of time can start to cramp one's hands causing the game to be painful to play. While this might sounds deal-breakingly bad, it should be said that as long as My My Katamari Damacy is played in small bursts of one or two levels, the controls tend to be a non-issue and the game is still very fun.
