It is a shame this is your last game, your needle design is not bad at all, it could be slightly better, but certainly not bad, I do like a bit of your stage. The background is not as bad as the eyes as nickel's, and it doesn't get in the way so, I can't mind that too much.
As for Nickel's stage, the tileset does a bit on the eyesight , and a lot of the saves can be shot because there aren't any save blockers, is this intentional? If not that should be updated. I do like some of the jump design in Nickel though, so, that is a redeeming factor.
I had fun with this one.
