You can play the game here too if you want; just scroll down. Controls are WASD or arrow keys. The game has been tested in Chrome and FireFox, but I recommend Chrome since it seems to give me a faster frame rate.
If the game seems impossibly hard, it only means that you were very, very, VERY unlucky. Refresh the page to generate a more normal distribution of flora. Art and sound are quite lacking to say the least, but the game does have an "ending" so don't give up! I'll definitely continue working on it after the LD27.
The source code can either be viewed within your browser the standard way (it is entirely unobfuscated although not very commented) or downloaded in a zip file. It's not open source yet though so please don't steal. ;)
