Given the last five hours of inactivity, and there only being 4 votes on the wishlist. I kind of guess you are part of a true minority at the moment.
I honestly never knew there was a PC version of the game. I thought it was NDS only.

Here is the wishlist entry.

Me too! I don't get the impression that the developer is at all interested in selling outside of Steam.

I played and enjoyed the first one (on DS). I would say it's a 3-star puzzle game, at best, but it's still fairly enjoyable. I certainly wouldn't mind checking out the new game.

Cool to see that they're making another one! I played a demo of the original for DS years ago, and I've considered buying it since.
