Water Glass Block

I liked the game. I'm ostensibly on level 208, but I swear that the past bunch of levels I've played before. I read another review that said that the puzzles repeat. Why?? I was thinking that somehow my progress hadn't been saved. But is that other user right and they puzzles repeat or what? Am I going insane? I think I'm just going to have to delete the game so that I'm no longer questioning my sanity.

This cute game makes you think about how you’re going to plan your next move and that’s fun. One issue is I wish there were different skins for the glass
