Floppy Birb is a funny game!

It’s fun!

This is the game I'm teaching first in my class on PICO-8, as it's an excellent example of what skills are needed to make a game. This has a basic form of almost everything and it's the best game to make when trying a new engine.

You did a great job for your first game, obviously, there's room for improvement.
The biggest suggestion I have is to look into the btnp() custom delays, found at poke-ing 0x5f5c and 0x5f5d.
Setting it to the lowest value will make it so the flap doesn't occur by just holding the button down. (It will repeat every x frames without altering that value, so this is handy in many other situations too!)

Keep at it! You did great for the first one.
