    Title: Runaway Train Concept: Runaway Train is a platform game where players must jump and avoid obstacles to save passengers aboard a runaway train. The player controls a character running through the train's cars, jumping over obstacles such as crates, barrels, and boxes to reach distressed passengers. The twist is that the train is constantly moving, so the player must be quick to avoid obstacles and save passengers before it's too late. Players must also collect coins to increase their score and buy upgrades for their character. The game becomes increasingly challenging as the player progresses, with faster and more dangerous obstacles.
