Difficulty steps up quite a large amount when you get the lazers coming from two sides at ones. It's way to easy before that.
Although the power ups are a good idea, the slow time and the invincibility ended up being time for me to just sit there and soak up the points.
Very different to the first game (especially with the mouse) but still enjoyable.
Interesting game, however disappointingly short. It would have been nice to have some unlockable things for getting certain times as the 'best time' is pretty stupid if you can't see your times from the menu or replay certain levels.
Boss levels are amusing for a little bit but the normal levels (especially the survive ones) are so repetitive that they are a chore to complete. Defiantly wouldn't have played this if there wasn't a badge.
