Major Gameplay-loop Update

New stuff

• Z button now does a boost! (eats up lots of energy though, be careful)
• Sprite rotation on ship
• Several new head & body designs
• Camera system & larger map
• Note: map graphics are very much a WIP!
• Collision and player physics tweaks

New gameplay loop

• Collect specific creatures that the Mothership requires (head + body combo, any colors) - shown via hologram
  • Each time the correct creature is collected, you will see more of the star-field and be shown another creature hologram
• Once 3 correct creatures are collected, you will "go to the next planet"
  • Mothership creature hold will be cleared, your star-field will shrink, and you see a new planet name
• Note: you now have much more energy, but it is still a concern -- so keep an eye on the yellow bar above your green ship!
  • Docking with the Mothership will replenish energy
