From below - TIC-80 256 bytes

An attempt at doing a city and using a display hack (minsky circle variant) in a creative way. Lots of work trying to fit everything into 256 bytes.

The initial idea was very far off this and was some kind of flying insect with a moon backdrop.

Layered integer circle algorithm. Lua code packed with Pakettic.

was iterating on colors on this version; liked the structure / darker colors
