great game, 5/5. on the outside the box thing you just jump against the wall on the left. If you need more help there is a full walkthrough at http://ahkong.net/super-karoshi-walkthrough/
shimmerz: the best projectile is the bomb cluster, after you get past the first 4 in the front, aim for the base of the big castle and watch it topple over!
great game btw. 5/5.
to save you have to go outside of a town and hit the little screwdriver that says opt. then you hit save game then save your game. it took me a while to figure that out to.
