Sure, just replace this lines
Code:
			player_dist.x = (key_w-key_s)*8*time+joy_force.y*4*time;
	
			player_dist.y = (key_a-key_d)*4*time;
			
				myangle.pan =-7* (key_e - key_q)*time+joy_force.x*2*time;
				c_rotate(player,myangle,ignore_passable+glide);

by this lines:
Code:
			player_dist.x = (key_cuu-key_cud)*10*time+joy_force.y*4*time;//8


			if(key_ctrl == 1)
			{
				player_dist.y = (key_cul-key_cur)*4*time;
			}
			else
			{
				myangle.pan =-7* (key_cur - key_cul)*time+joy_force.x*2*time;
				c_rotate(player,myangle,ignore_passable+glide);
				player_dist.y = 0;
			}
