Fix CTRL working

[Arta48]

I'd fix it like this

keyboard_mouse.py:

import pyglet.window
    
import controller
import math

W_pressed = False
LCTRL_pressed = False

class Keyboard_Mouse(controller.Controller):
    def __init__(self, game):
	    super().__init__(game)

	self.game.on_mouse_press = self.on_mouse_press

	self.game.on_key_press = self.on_key_press

	if not self.game.mouse_captured:

		return

	if button == pyglet.window.mouse.RIGHT: self.interact(self.InteractMode.PLACE)
	elif button == pyglet.window.mouse.LEFT: self.interact(self.InteractMode.BREAK)

	if self.game.mouse_captured:
		sensitivity = 0.001

		self.game.player.rotation[0] += delta_x * sensitivity
		self.game.player.rotation[1] += delta_y * sensitivity

		self.game.player.rotation[1] = max(-math.tau / 4, min(math.tau / 4, self.game.player.rotation[1]))

def on_mouse_drag(self, x, y, delta_x, delta_y, buttons, modifiers):
	self.on_mouse_motion(x, y, delta_x, delta_y)

def on_key_press(self, key, modifiers):
	global W_pressed, LCTRL_pressed

	if not self.game.mouse_captured:
		return

	if key == pyglet.window.key.D: self.start_move(self.MoveMode.RIGHT)
	elif key == pyglet.window.key.A: self.start_move(self.MoveMode.LEFT)
	elif key == pyglet.window.key.W:

		LCTRL_pressed = True
		self.start_modifier(self.ModifierMode.SPRINT)

	elif key == pyglet.window.key.E: self.misc(self.MiscMode.SPAWN)
	elif key == pyglet.window.key.F: self.misc(self.MiscMode.FLY)
	elif key == pyglet.window.key.G: self.misc(self.MiscMode.RANDOM)
