lol on one of the levels i was sitting on two of those explosive blue things and a guy shot it and i flew high as onto a roof and just dropped down to the end of the level =]
very easy, i got three quaters of the way on hard before i died the first time, and then i only needed one respawn, the respawns make this too easy. 3/5
got to lvl 10.... the movents of the block dont work with the movements of the game so it makes it very hard to complete some levels... great game though =]
