Ver.1.7.0
・Fixed a bug where the upgrade button was blocked by text and couldn't be pressed.
・Added the ability to fire using the right stick.
・Added the ability to change firing direction with the right stick.
・Changed the system so that during gamepad or keyboard firing, the firing direction is maintained even when moving the spaceship. Releasing the firing button will reset the firing direction to match the spaceship's orientation.
・Changed the upgrade "PW Bullet Speed Up" to "PW Power Increase."
・Added a function to display "Controls" in Settings.
