This is a cute little entry ^^. Don't get me wrong, the gameplay and graphics are really simple, but it's really cute for a first game ^^. And honestly, I was surprised to see how, with just a couple of shapes and colors on the screen, I always understood what to do. Touch green thing => open green thing. Grab purple thing => bring it to purple thing. It always felt natural, so great job on that!
Oh, and you should add a screenshot and a description to attract more people to play your game =).
