This is much better. I can actually move the pieces around. There's still a couple things I think could be improved, though.

The solution should be pictured somewhere. I "solved" the puzzle one way, but it didn't register as solved, so I hit the "Solve" button. It showed the solution for a tiny fraction of a second, then blanked out with the "Victory!" screen. So I tried to replicate the solve on the next try. I believe I placed the pieces correctly, but again it didn't register as a solve. Hitting the "Solve" button again didn't seem to change the pieces in the brief 1/4 of a second (or so) I had to see the solution before the "Victory!" screen. I think slowing down the "Victory!" screen or making it not opaque, as well as displaying the correct configuration, would improve playability.

I do like how the moveable pieces are highlighted and how smooth they move. And the simplicity of this interface is refreshing, although you might want to include a way to mute the music.

I used to play this type of game as a kid 30+ years ago, so seeing it in digital form is a nice reminder.
