I'm sorry but I didn't quite understand what you said. There are no levels, the maze is generated randomly each 15 seconds. The maze is just a placeholder for what the real adventure is! Have you gotten past 10 points? :)
If you keep going, the tumbleweed will come back, and you will witness something else. Again and again, until the end of the game. Haven't you noticed how the game screenshots look all so minimalistic but the game does not? Something tells me you haven't even seen the tip of the iceberg hehe! :P
