A lot of thought went into the artwork, graphics, and gameplay. Unfortunately, for a game that uses the history of typography, and hence language, as its universe, it's a little disappointing that as much attention didn't go into the written parts (or got lost in translation? Either way.) There are typos, misspellings and bad grammar. Parts of it are not well written or edited, which at times made them seem more like info-dumps than essays, and made processing the information uneasy. Hence 4 stars rather than 5. I was occasionally frustrated by the difficulty, esp. with the bonus level. When there is too much luck rather than skill involved (i.e. when spinning obstacles are facing the wrong way) and you have to repeat over and over and over it ceases to be fun. There is a very simple and elegant control mechanism - touch one side of the screen to move and the other to jump. However, it could use one more element to give you a bit more control. Despite that, I did enjoy it and recommend it for the creativity, unique mechanics, length, great soundtrack and immersive quality.
