very good
we need more games like this: no load times, simple controls, fun platform adventures. however, the one thing i would change is the speed: sometiems i would be waiting for an enemy to go a certain way, and it would take forever! that would get pretty frustrating, as well as the unrealistic physics when i jumped into a wall or something (or a ceiling)--at least from what im used to. however, overall, very good game, i felt that it waisted my time quite nicely, actually.
