I had lots of fun with this, it feels like a top-down roguelike version of Fruit Ninja or swordfighting in Wii Sports Resort! Very nice visual effects on the hits, and the physics based nature of the sword works really well because you can parry attacks either by blocking them or by hitting them. I took almost exclusively fast hand upgrades so I could just spin it around extremely fast lol. My only problem is that there isn't much variety in upgrades or enemies, and the gameplay started to get repetitive after a while. All in all though, very good game!
