This is a very frustrating physics platformer. Your patience will be tested, especially towards the end. So only play it if that's what you want.

There are a few real puzzles, but usually the puzzle is "how do I get this box in this position without stumbling". Nearly every jump you do, you fall on your fat belly and have to rewind (he's unable to get up). Unfortunately the maximum rewind time is limited, so you can easily create an unwinnable situation for yourself and have to reload a checkpoint, which conveniently has a dedicated button and is instant.

The game is surprisingly polished, with voice acting and beautiful typical Japanese environments. The main character is friendly and innocent, which helps alleviate the frustration. It took me 6 hours to complete the game, ignoring the collectibles.
