Some of Pixel's lesser-known games could be coming to WiiWare or DSiWare.
Nicalis hinted at the idea of publishing Ikachan and Guxt, two of Cave Story creator Pixel's other games, in a recent blog entry on their website.
In 2009, Nicalis talked about the possibility of bringing Pixel's other games to DSiWare on Twitter.
All of Pixel's games are available as freeware online, but Cave Story was released on WiiWare this past March with upgrades.
