Fix for Mantis Bug

What's changed: - Fix for a literal bug where a mantis limb would appear in place of the battle axe - Fix for enemies getting stuck on platforms in zone 1 - Minor audio adjustments and fixes Huge thanks to everyone who has reported bugs and issue lately, and to everyone thanks for playing! I'm excited to bring a bigger content update in the coming weeks, which will expand the players max level (new starter items!), and bring more variety and customisation for when the player is transformed. Cheers! -Adam
