Show HN: Flappy Bird in Google Sheets Using Only Formulas

Hey, I built Flappy Bird in Google Sheets w/o using App Script. It's entirely built using cell formulas, conditional formatting, and an unpatched server side validation. (I learnt of it's existence here: https://docs.google.com/spreadsheets/d/1KAauJp9MiblyAInIbgS2ndc2ArAmnhd1FIODYZEVFHc/edit?gid=1654097081#gid=1654097081 https://docs.google.com/spreadsheets/d/1KAauJp9MiblyAInIbgS2...) I decided to build this after coming across https://eieio.games/blog/realtime-google-sheet/ https://eieio.games/blog/realtime-google-sheet/, though I think in some ways mine's a lil more advanced.
