Made by a kid and his dad
Nitro Burst started in a notebook. A boy who loves cars drew up 95 of them, gave each a name like "Mr President", "Blood Chef" and "Gold Mines Burst Out", sorted them from Common to Special, set their prices, and invented level names from "Trash" all the way to "Max". He even planned a screen for trading cars with friends.
His dad wanted to see if those ideas could become a real game, so the two of them built it together, by talking it through and testing every version. The son tried each change, said what was fun and what wasn't ("hold to go, not release!", "the timer is annoying"), and the game kept getting better.
That's what Yarkade is for: any kid's notebook idea can become a game they actually play, test and keep improving.
