Word Chain is a simple and compulsive word game. It's the first Flash game that I've written having been introduced to Flash by writing a route map for my work.
There's a tutorial in the game but here's some further instructions...
Make new words by changing a letter in the current word.
Using the mouse or keyboard, select the letter in the word you want to change, then click a letter on the pad to make a new word.
Turn on all the lights to increase the score multiplier.
Each word scores the total of the letters plus time bonus multiplied by the multiplier.
Remove the last word with the back button if you get stuck.
The game is over if the time runs out.
Later levels are made more tricky by less time bonus and disabled keys.
UK or US dictionary can be selected by clicking "Options".
