Just a quick patch to add some small quality of life changes here and there. I'll have a bigger update with a new boss out hopefully by this weekend.

v0.13.2 Updates
- Added a lives indicator in the top left when in-game.
- Added the ability to restart Endless Mode by holding down the start button (also works with the escape key).
- Increased powerup drop rate and the amount of energy they replenish.
- Changed the menu font to minimize the UI size.
