Extremely polished and pleasing game! The balance is a little off, I felt like even just removing the entire health bar and replacing it with instance game over might've been better, but the game is still very nice to play simply because it's so well put together. Also there's a small bug with restarting, because it won't actually reset the timer or any of your resources. Great job though! You could really expand this into something worthwhile if you kept working on it.
