that game is cool... i think you might could clean up the front page a little... to make it more obvious... but the idea for the game is great! did you make it yourself? do you make lots of games? do you do this full time?
It's just me working on the game, part time right now, and it's the first game I've made.
So be one box that has: " click as few links as possible to get from "Banana" to "Britney Spears", as fast as you can!"
where Banana and Britney Spears are replaced with your actual words.
2) have a very clear "start" button. It's not clear without spending a few moments to understand to click the first term to start the game.
good luck. it's a cool game... another thing might be to show an example or some strategy tips. that might not should be on the first page though...
