I loved this game and found it really easy and simple to play. Its a game my children could very happily play without getting stuck every two minutes.
The concept of the game is simple, you pick a character, who is your 'driller', there are a few to choose from and each one has its own 'specialities'. You are then sent to drill!
Its all about drilling as far down as you can get, the further down you get, the better your score. Along the way, you have to avoid getting squashed by falling bricks, and you have to catch 'air'. As you get lower, your air supply begins to dwindle, so you have to make your way through the bricks catching air bubbles to be able to continue.
Each level, the bricks change, different colours and patterns to add some variety to the play.
Its a really good game and Im happy with my purchase!
