Completed game 100% and captured every single creature available.
This game plays relatively fine, but it does have drops in frame rates. Specifically when loading into a new area, the frame rate drops and it takes a few moments for the game to "catch up," so to speak. There are moments while in an area, where the frame rate will drop for no reason as well, so the game has some frame rate issues.
Biggest frame rate drop noticed was during the boss Megamaki. This particular boss splits into portions when you hit it, and when the boss splits apart, the frame rate heavily drops. Again, the game will eventually catch up and will play normally, but the frame rate drops are still noticeable. Some parts are more noticeable than others.

Didn't notice any game breaking bugs or any other bugs other than performance.
Graphically the game looks pretty good in handheld mode, but in docked mode it does look a bit washed out.
