You're welcome!
I'll post some recommends too, some have been FAOTD too.
Practically anything from 10tons Ltd. I've recently finished
Azkend and
King Oddball. Both very good games.
I've recently discovered
Feed Me Oil (published under Electronic Arts Inc.), and
Contre Jour from Chillingo.
You have to buy the puzzle packages separately, but
Puzzle Retreat by The Voxel Agents is great too. If you like Quell, you'll probably like this as the gameplay is similar.
