Slitherlink worming its way into my heart

(tags game, Dual Screen, puzzle)

I don't know why but I woke up in the middle of the night. I decided to try out Slitherlink because I thought it would be quick. I ended up playing 20 levels which took probably about an hour and a half. I am slow. Also I seem to be fighting the control scheme because either I mistap or the game misinterprets. I want the controls that mark the current box to be on the left (D-pad) instead of on the xyba buttons. I shouldn't have started it, but now that I have a taste I am trying to finish Sudoku Deluxe as fast as I can.

Here are my results for the first part, "introduction" (入門). Not very flattering.
