Update 1

Added a WebGL build of the game. Fixed a few of the most mentioned bugs. Added a bunch of new features and tweaks. I'm thinking not to do too many updates to this, as it was just a simple jam game. But for the experience, I'll do the ones that make the most sense while trying to keep the package tidy!
The downloadable version is still the one that was rated in the jam!

Bugfixes:

• Resetting score value
• Score text dropping to the second line when over 1000
• Wind is now being added separately as a physics force rather than added to the control.
  • The results for the first implementation were, shall we say, unwieldy

Features:

• Wind indicator (flag flapping to the approximate direction of the wind
• Smooth movement
  • Rather than move instantly, there's buildup and slow down to the regular movement
• New hazard types
  • Added a "wall of death" type spawn for the spikes
• Tweaks to the game loop
  • Increasing difficulty
    • The game gets faster and more hazards spawn as a round completes
  • Different spawn intervals
    • Different kinds of hazards have varying spawn intervals
      • E.g. the eagles are now being spawned concurrently with the next wave rather than wait for them to finish before starting the next one
      • Same for pickups
  • Added randomness to spawn directions
    • Used to be fixed direction (Left to right etc.)
• Invincibility 'Star cheeze' now grants actual invincibility (and you now have time to see it in action)

Future fixes considered to be implemented:

• Still getting a bit of stuff spawned outside the bounds
• Music should speed up along with the difficulty
• Accidentally left 'Idle' spawn state out or too short. Action starts a bit too soon now
• More spawn points for the eagles. More spawn points overall.
