i dont mean to sound to negative but the same could be said for any run. look at mega man x. all you do is run to the right and shoot. how boring is that.

But those later Mega Man games have to be among the most difficult to time attack because perfecting the sliding is so annoying.
Also, you should know, your partial solution is absolutely incorrect and has a fatal flaw. How are you going to fill the four empty spaces in your inventory after you float the cube in your cursor? If you don't know, you cannot drop the Cube, or else everything inside of it will come tumbling out.

That's what rerecordings are for!
