version 0.3 released

Fixed a few issues that were still in the game after the last bug fix. Also changed a few things. I feel like it changed enough to warrant calling it 0.3.

Changes:

• Added smoothing to health bar when taking damage.
• Highscore now resets for each new version of the game.
• Purple bugs are no longer insta-kill, instead reducing your health by 25% of its maximum amount.
• Purple bugs are now lighter
• Purple bugs now jump with less force
• grey bugs no longer die quicker after touching a corpse
  

Fixes:

• Purple bugs no longer eat their offspring. (they were doing this immediately)
• Baby purple bugs no longer clip out of bounds when jumping.
