148apps: Save Sylva is a solid fixed path tower defense game that will drive you nuts (in a good way) because of its insane difficulty. Pick it up if you’d like a challenge.
AppSpy: 'Save Sylva - TD' is challenging without all of the brutally frustrating required replays to get your build order 'perfect' making this a great game to kick back and enjoy.
It alsmot looked like Pixeljunk Monsters, from the little picture, but looks intresting enough, I would play it if it were on a console.
