This theme had me stumped. I basically needed something that could be “arcady” and “simple to do” while encorporating “Evolution” somehow

In some flash of inspiration, I went from changing animals, to Knights/people, to…spaceships. The game is going to be a Gradius style shooter, and as you fight, your behaviors will “Evolve” your ship. Your enemies should do the same: kill them right away and they become faster, start moving differently, ect. In code, it’s easy to switch a bunch of variables, but I need visual change too.

To accomplish this, I created some bits of ship, and then tacked them onto each other, right now it looks like this: Off to a pretty good start.
