0.6.4a Game balance and control help

Two out of the four goals planned for 0.7 have been completed.

• Game balance changes
  • Extra lives are now given at the first 2 million points and every 3 million thereafter.
  • If you lose a life, your first four teammates die with you.
• More helpful control instructions
  • In the Controller options, choose from one of four popular controller types: Xbox, PS4, PS3, and Nintendo Switch. The tutorial and other in-game text will refer to controller inputs by their proper names. (For a PS1 or PS2 controller, choose PS3. For a Wii controller, choose Switch.)
  • If you have no controller, the game refers to the keyboard controls instead.
  • The game updates the menu and text when controllers are connected or disconnected.
  • The custom button naming ("other" controller type) is WIP. I am not sure if there are enough nonstandard controller users to justify it.
• Bugs fixed
  • Inaccurate touch and mouse coordinates made menu buttons harder to hit.
  • Tall trees in stage 1 were missing some of their cover hitbox, leaving enemies vulnerable when they should have been in cover.
