The Good
If this kind of puzzling gameplay floats your boat, you're going to really enjoy Let Me Loose, and there's plenty of imagination at play in the level design, particularly once you get passed the early days. It's a pretty good-looking game that kids are going to love too, although they're not going to like the difficulty curve all that much.
The Bad
That difficulty curve is insanely steep, and the real incline begins right after you've been shown how to use a premium item to fill the level with water, and then float with ease towards the finishing line. That power-up by itself feels a little cheap, and the fact that it's introduced just before the difficulty ramps right up will bring out the cynic in anyone. The tilt controls are also very rigid, and you'll have to keep your device absolutely level while tilting left and right.
The Verdict
Let Me Loose wouldn't be our first recommendation to anyone who'd yet to set eyes on a mobile physics puzzler, but if you think you're up for a serious challenge then you might want to check the game out. Even then, you can't help thinking this should have been a free download, with premium level packs for those at ease with the challenge. That would have allowed everyone to test the waters first.
