Claybook is a physics based platforming game. Each level sees you taking control of various shapes (ball, cube, cylinder, and disc) and you're given a mission to do, such as going through all waypoints, moving items around, etc. The majority of achievements are miscellaneous achievements specific to a certain level, so you'll only have to progress far enough to unlock all necessary levels for achievements, and then you don't even have to complete levels. Just load them up and get the achievement in them. Since it's physics based it could be really quick for you or it could be a struggle while you get used to the handling and controls. Either way, it's still a pretty simple and easy game.
I'd first like to point out that much of the information you'll find on the internet was published about this game during its game preview phase. Since its full retail release, the chapters of levels have been reorganized and level order has been shuffled around. This guide references all of the levels in their order for the retail release.
The first thing you should do is progress by earning 3 stars in some levels. First off, the first book consists of the tutorial and three levels. Get three stars in all of these levels and you'll make great progress. Refer to the "Polished to Perfection" achievement solution for more tips on doing this easily. You need to earn three stars on all levels in a book, and the first book is easiest, so best to do that first.
With the first book done, the second book has some easy levels too. The first one is very simple - just "eat" the chocolate and eat as much of the bridge as possible to get up to 100%. You should be able to get three stars pretty easily in this level. The second level, Cake Rush, is even easier. Just roll through all the waypoints, using rewind as much as you need, and you have to get three stars. The third level is similar to one from the first book. Make small trenches from each tank to the center pit. Push fluid yourself if need be, but 2 stars is enough here. Now on to the fourth level, Cannon Castle. You need to finish this level in one go without rewinding. It's not bad at all though. Refer to "The Great Escape" for a video and tips on how to do this. You'll unavoidably get 3 stars on this level when you get this achievement.
Now you'll have access to all of the levels you need to get all of the miscellaneous achievements. Refer to the guide below for each achievement and which level to get it in.
Claybook is a really simple physics based puzzle game. The levels aren't complicated at all, and the controls and tasks shouldn't leave you very frustrated. The rewind function can be used whenever needed aside from two achievements, making it a pretty casual experience and a pretty easy completion.
