A masterly example of sparse efficient writing. free bird relies on adjectives and nouns alone to paint the setting and the elements of note within it.
Without elaborate (or even short) sentences and turns of phrase, it highlights only those words that are crucial to the game. However, the game world feels rich and open because of the very clever choice of words and particularly of adjectives. An adjective-noun description of a sickly iguana reviving when its warm light is turned on triggers an entire story and a sequence of rich images in the mind in a lot less words than this paragraph I just wrote about it.
The puzzles are clever, it took me some time-outs to get the solution worked out in full. Because free bird is a click-based game, it would probably be possible to mechanically brute-force the solution a bit easier than it would be in a parser. But then, why would anyone play just to take the fun out of it…
Very clever use of language, nifty puzzles with limited resources.
A great protagonist accompanied by an interesting cast of supporting characters too. Again, despite (or thanks to, depending how you interpret it) the self-imposed language limits, their personalities are clear, with a few poignant details shining through to mark their most important traits.
I liked this very much.
