Well it started with setting some constraints: I won't have much time to work over the week and I want something that will be at least semi unique (I didn't want to do a gambling game since I figured that's gonna be the main interpretation.
When I started brainstorming I quickly came to a realization that I will need an arcade game if I want to finish this on time and from there it was mostly just the fact that I was watching some videos about a building game where someone was constucting a plane and I figured dogfights kind of happen in big circles so that could be work.
