Saw this over on DigitalSpy.
Trouble Witches NEO! is currently on sale at 400MS (normal price 800MS), which is incredibly good value, as part of Xbox Live's Deal of the Week.
I'm not sure exactly when the deal runs out but for that price i'd recommend picking it up, i've done a short write up about it in the past and just to note the game has actually had some good reviews in magazines and on other websites.
Check it out on Xbox.com.
