Don't believe me? Here's a quote from NintendoLife:

One of the most anticipated WiiWare games was released a couple of days ago... Cave Story! And guess what? One of my friends -- Tyrone Rodriquez -- is the publisher! His company is called Nicalis. I am extremely proud of him... this is a huge deal! Cave Story is absolutely awesome and it has been getting rave reviews. If you have a Wii and you want an old school style game with killer gameplay, you owe it to yourself to play this game.
