I'm in a bit of a hurry so I'll write more about this later. But I'll just say that it's an homage to Blaster Master, and that it's a really engaging game. Gameplay switches between 2D and 3D, and involves exploring large areas to find new abilities you can use to progress.
The graphics/visuals are easily the weakest link here, but take me word that it does look better in motion than it does in the screens. They're not great, but they're not offensively bad either.
