Cave Story is still yet to be released outside of North America, but Nicalis has already started putting out a few hints that it may have further collaborations with Japanese super-talent Pixel.
The site's latest blog entry shows an intriguing image of two characters from Pixel games Ikachan and Guxt. Like Cave Story before, these are both freeware games already, and despite a quizzical Tweet last year where the company casually asked about which title gamers would prefer to see on DSiWare there's nothing else to go on.
Is Nicalis just teasing or does it have further plans to bring more Pixel games to the wider world? When we know, you'll know.
