New sounds/softlock fixes!

Simply added sounds and patched softlocks.

Thank you everyone so far for playing my game, it's very short and I would merely call it a short tech-demo in it's current state, but I will 100% be spending significant time and effort towards a full game. Planned to become a full MetroidVania rather than a linear puzzle-platformer, this will definitely become a much much longer and fuller experience. Even been exploring the concept of a roguelike interpretation of the mechanics, so that's intriguing ;>

Stay tuned for more (and probably frequent) updates and expansions! :>
