Nice game.
The graphics and sound are well-done and everything fits together.
I like the idea for the resource system, although the game may need to be harder (and have more varied difficulty over time) for it to feel impactful.
The game becomes uninteresting after learning how to play and surviving for a while, and it needs either a win condition or a scoring system to feel complete.
The camera shifting based on where you aim is slick, very nice.
Well done :)
