TRUpuzzlE is very similar to Wriggle and Snake Slider. The object is to slide the chains around so that the green chain gets to the green squares. The puzzles are very well designed. The order of difficulty is not sequential. Level 25 was much harder for me than some later levels. That's a minor complaint.
The steampunk art is only in the one image.
There are 56 levels and I solved them all in about 2-3 hours over two days.
Note: this game is temporarily free, so get it right now.
