Like Flappy Bird, press to make the butterfly/bird go up. If you hit a building or one of the polite dinosaurs, you will die. Storyline: You are a crappy bird/messed up butterfly trying to destroy the city. The polite dinosaurs are trying to stop you, so avoid them as well as the poison covered buildings.
@Ellajaneholm did some of the art. Background from Adobe Stock. Enjoy @Tanjiros_Socks did a small bit of art and all audio (yes, the music is supposed to sound messed up)
