0.0.11 - Health!

A core design pillar of this game is simply the phrase 'Shark Souls'. It gets a little boring blasting through endless waves of paper enemies, so I gave them a little tenacity :)

Features:
- Added health and health bars to enemies

Bugfixes:
- Occasionally enemies would get stuck and stop moving on exiting the pause menu.
- Wave number in the corner incremented early.
