We have no way of knowing what HAL Laboratory is up to. All we can do is look at their website and virtually thumb through what they've posted. That's exactly what reader Shiine did, and he found some interesting stuff.

If you visit their official Japanese site and click on the 'idea cube', you are presented with a bunch of art that looks like it's related to Canvas Curse. The thing is, a lot of the stuff we see was never used in the game. Were these ideas that had to be yanked from the original, or a collection of works that may appear in a sequel?

I would love a sequel to Canvas Curse!

Looks like stuff for a sequel

Just looks like spillover from the original, to me. Why would HAL leak this stuff for the world to see?

Yeah that game was great, would like to see a sequel for DS.

I never did have that game. Now thier are just to many Wii And DS games I want.
