Glow HD is on sale, but the comments in the AppStore have me hesitating.

Anyone have this game? There is one review for the newest version, which gave it one star, saying that a full screen advert has been added.

Can anyone confirm or deny this? I'm also looking at lightopuss and Osmosis, now that the later can be played on an iPhone. Any other artistic games to be recommended (from what I've read, Nilhunbra sounds like it will just frustrate the hell out of me)?
