GamersFTW has played right through all 30 levels of Keebles and has given it 7/10.
"Keebles is a physics-based vehicle-building puzzle game which marks the first game by Australian Indie developer Burnt Fuse. The game requires you to build a range of wacky contraptions in order to save a race of small fur balls and make it to the end of the world. Trial and error is the key to this game requiring you to firstly perfect a vehicle capable of traversing the environment and secondly guide it to the goal through the use of your gadgets."
