You can also directly influence the fuel consumption by packing lightly. If every Finnair passenger would have travelled with one kilogram less baggage in 2018, the fuel savings would cover 20 flights from Helsinki to Tokyo." Reference: - ninjahoahong

In the demo, I have played a level using special skills such as the magic guy to re-arrange the layout and the "powers-up" to bomb a large area. There is
