For now, I'll just give a quick run-down of what this game is about. In Master Plan you take on the role of Mad Scientist Supervillain who attacks the city and his heroic nemesis in his personalized mechanical engine of destruction.
At the start and near the end of this run-through, you can catch a glimpse of the vehicle editor used in the game. All of the objects with glowing rings during the main game are components the player collects to use in that editor.
Over the course of this play-through the vehicle becomes larger, more dangerous, and more garishly adorned with blinking lights due to the changes made by the player in this editor.
Conversely, these pieces can also be blown off of the player's vehicle by enemy attacks, allowing them to disarm and eventually destroy the machine.
