I think the premise for this game is pretty cool. There is this thing where you can recognise a word as long as the first and last letters are the same as the ones in the original word. so challenging that is a great idea.
The reason that I am only giving this game 3 stars, is because of the GUI and the music. Let's face it, there is nothing visually arresting about this game, in fact it is just average and the music is kinda dull.
All that said though, I love the original idea and I hope you keep making games like these
