Doors provides you with a simple challenge - can you open the Door in front of you? The problem is not in defining the  last move (that's easy, tap on the space behind the open door), but how you manage to open the door is the problem. Each level is a self contained 'point and click' adventure. How many doors can you open?

It starts out relatively easy - just click on the door and it opens. As you go further into the game, you need to start thinking hard towork out the puzzles. It's easy enough to move a welcome mat to find the key, but when you have locks that need combinations worked out, jigsaws to solve, and even the use of the accelerometer on your handset to physically make a move, that's when 'Doors' becomes a little gem of a game.

You are going to need to think laterally, you will need to look at the screen for every single clue, and yes, there might be a level or two where you'll just click aimlressly, hoping to find some inspiration.
