The instructions are in-game. Full screen recommended.
Thanks to Don Nyguen for making Flappy Bird, this is a rip-off of that game. I was actually working on personal projects on Scratch 2.0 offline, but since I didn't share anything on online Scratch for a while, I decided to share this. A remastered version, much quicker and controls more like the real game: https://scratch.mit.edu/projects/616962211/
