It has the compile magic, at least it is technically one of the most impressing piece of software on the system, which speaks for compile work. but uberlong and halfway dull levels kills a lot of that magic.
If they didn't had implemented those annyoing bonus stages (or just available as a separate omake game on the cart) and the general levels would have been cut back to 1/3 of their initially length, the game would have been quite very good.
