Not great, but alright concept
Not a bad idea for a game. You need to put more effort into the graphics. Maybe think of a metaphor for the game, like Operation we played as kids. Maybe something that has to find its way through a maze. And make it obvious what you are doing. Clear instructions for the game as an introduction. One last thing, for all your buttons that are text, you will notice there is a 'Hit' state inside it. This frame is where you have to have your mouse over to click them. Drag a box of any colour over the text in this frame, that way you can click on the buttons easier, instead of having to click on the actual text, instead of the area around it.
Anyway, give that a go and good luck.
