v1.1.0 - Various quality improvements!

New sets and bosses will be coming eventually, but for now, have these quality improvements

• You can now sneak by holding shift (or left trigger for gamepad). This will make you move at half speed for precise dodging.
• Some visual changes to make shooting enemies more satisfying.
• Fixed some broken mechanics.
• New main menu and play menu, which comes with new statistics. Unfortunately, this means all of your previous data is unusable... but it was bound to happen anyways.
• Some gameplay changes and balancing.
