[UPDATE] Memory Leak Fix

Came back to make some changes and realized that the game had a memory leak, so I cranked out a quick fix. Sorry about that, still learning the ins and outs of Godot and had no clue about how to check orphaned nodes when I first published! There's also some small tweaks, like automatically shooting, and an item display! More stuff in progress but these were done be the time I noticed the leak, so they're coming with the fix.
