Creative take on the theme. The game is very hard though but perhaps this was intended. Opening the shield is a little weird though, you should either have it be opened while holding the button, or have it be toggled by pressing the right mouse button. Now if the player accidentally holds the right mouse down too long it will open and close instead of just opening. The music and art are very well made, I like it a lot. Overall the game is enjoyable. A solid submission, good job!
