There`s more coming in the future. We plan to do a full design on the bullet(protagonist’s shuttle) designs of background characters and more.
Why we put the plane together with the characters? Because animators need to perform everything like an actor/actress. There is certain ways to show a happy person, there is also a certain way to show how a plane fly. We treat our little plane the same as our characters. It serves a lot.
Most of the big artiliary has an issue of unable to ignite all propell fuel at the same time, causing great loss onf propell power. Schwewer Gustav, world’s biggest artiliary has this issue, causing it has far less power than it was designed to have.
