Hello, got some feedback for you :)
First of all, love the menu. The only problems is that when you click on the credit button, you get take to the page without any way to get back. Great music and sound effects for the game. Love the idea of the game. If your still going to continue development of this game, maybe looking into adding a little post processing. It will add that extra refined touched to the game.
Keep up the good work :)
