v0.2.2

Updates:

• Added fuel system! When you use your ships engines, you will use fuel. If you run out of fuel, you will be stuck in space! Conserve your fuel and collect crystals to refuel in the port. Remember: selling green crystals = 50, yellow crystals = 100, refueling costs 1 credit per 1 fuel unit (max of 500).
• Buying fuel will fill you back to max fuel. If you are at 200 fuel remaining, it will cost 300 credits to refuel. If you are at 95 fuel remaining, it will cost 405 credits to refuel. This is currently no 'buy partial amount of fuel' (as noted in the bugs below).
• Added shield/hull UI (currently non-functional)
• Now saving fuel, position, and rotation of player when you leave the game, so you don't end up back at (0,0) every time you start the game. This helps prevent cheating if you're super far away from the port, and helps prevent misfortune if you're really close to the port with barely any fuel, and it sets you further away.
• Keys 1 and 2 decrease/increase your fuel by 100. This is only a short term debugging feature because I am lacking the 'what happen's when I run out of fuel' events. More to come on those in future updates.

Thoughts/Observations:

• It's currently saving player position/rotation every FixedUpdate which is probably waaaaaay more than it truly needs. I may switch this to be 'saved' by going into the pause menu and hitting 'Save' or 'Save and Exit'. This will allow for reloads when you really goofed up and don't mind reloading. I don't mean to make the game so utterly punishing that you can't simply reload a save. However, in the mean time, it is what it is.
• The fuel system has really added a little bit of challenge to the game. The game will be very punishing if you just hold down the keys. It forces you to really try to conserve your fuel and go for the convenient crystal coming by and makes you determine whether that yellow crystal going by on the side of the screen is worth it or not.

Bugs:

• You wont be able to refuel if you don't have enough credits to fuel up to max fuel. To resolve this for now, use key 2 (if necessary) to add some extra fuel until you can afford refueling again.
