the game is hard to control with the keyboard. like many other flash games. the keys hang and hardly change once they are pressed. some systems handle the keys properly. those are the ones voting high rating. others might vote low. i guess this is the result of programming the flash using old AS2 method (ie polling the keys). instead, i wish all new flash games would use the new event handling routine for reading keyboard button strokes.
btw. about the randomness comments. is it possible to add the standard fixed strings plus a couple more random ones just in case? a little more coding i know. but all in all in the game in this state is great if one is really trying to pass for the puzzle rather than to just see what comes next...
