v0.0.0.2 changes

No new levels just yet, it's all bug fixing.

• Control change - keyboard numpad is no longer used. Now it's Z and X on keyboard.
• You can no longer bring up the pause menu when SPID is dead.
• You can no longer shoot worms off the platforms (which was making them float)
• Fixed water that was clipping through the tilemap on level 01, making it look all funky.
• Enemies no longer animate when stunned.
• Timer no longer counts down when dead (which was a problem if it expired when dead).
