Saujanya,
I liked the effort on the spaceship and the title but it I think having it out at the top tell the user the game is called Planet Beta and not the Spaceship.
I like the hover of change in colour of the buttons but you it lack the consistency of spacing between each button.
Also, a resolution change would've been good as well because not all users use the same type of screen size. A few of the Icons like the Move and Close button werent visible on my screen even in fullscreen mode.
