This is probably the best letter-game out there. In each level you are given a number of blocks which have letters on them. Every block can be moved horizontally, but some move vertically too. Your purpose is to compose a word out of those letters and then fit it into the yellow spaces. As you progress throughout the game it becomes more complicated: switches, property changers, sticky surfaces... The game also has a "funny" part: at the end of a level there is a short cutscene in which the word is pronounced and sometimes a short clip is presented. While most good games are too short, this one has plenty levels, 64 to be precise.
+ great levels
+ diverse gameplay elements
- too few hints for such a long game
