ok i did the whole game in only 2 shots. for the train, i just grab unarmored and throw at armored to make them unarmored and grab them to throw at the other armored and then grab the new unarmored to kill the other one. Timing and position are important for the time limit lol. For the one where u have to shoot the panes (the one with 3 armored) I just kicked one pane, and one the armored was unarmored i grabbed him, use him to destroy another pane, and shot the other panes.
