There's fun power-ups to help you along, including lunches made by your girlfriend. If she makes a particularly good lunch, it will transform you and help you out in battle. She's not the best cook, though.
We're really digging what we've seen of Hammerin' Hero so far. I miss good ol' platforming like this, and it's definitely welcome on the PSP. We'll be back with a full review closer to the April 7th release date".
