This was my submission for an assignment in a programming commercial game engines college class.

The assignment was to recreate the mobile phenomenon, Flappy Bird. Art style, points, and feel were open, but core mechanics should match. The player should control a character and fly through oncoming obstacles to gain points.

I wanted to make a nature focused game, and began browsing artwork on OpenGameArt. When I came across CDmir's beautiful monarch butterfly, I knew I had found the star of my game.

I tried to make a game that loosely follows the path that a migrating monarch butterfly might take on its journey south, as it passes through different regions, and dodges different predators.

All of the artwork, sound, and music used in this game are Creative Commons Zero licensed assets. The artists have chosen to make their work free to the world, and I thank them for that. This game would not have been possible with out their generosity.
