FANTASTIC ART! this totally made the difference, sometimes, for me, what makes me want to play a game is not the gameplay, but the art and the effort put in the small details of the game and your game is clearly it. It is a simple "start engine" but the art gave a way more professional look, this made me enjoy more than I imagined. Also the sound effects are really great and fit well in your game, congratulations for your project, for a newbie it was FANTASTIC. nice job !
