Really liked it, reminded me of Jet Set Willy. Not sure why there are so many comparisons to Shift, as other than the gravity redirection, there's little in common. Still wouldn't buy it mind, maybe if it was cheaper.
Not quite sure why people are whining about this being a copy of other games, most Java games tend to nick from everywhere else. Desktop Tower Defence wasn't the first, and won't be the last. Anyway, this is decent enough, fairly easy but at least you don't need to juggle the damn things. 3/5
