Press X to exit the hive, then use the arrows to get to a flower. Hold O to collect nectar. Then return to the hive, press X to enter, and hold O to deposit the nectar. When enough nectar is collected, you win.
(X and O are the Pico-8 buttons, which probably aren’t mapped to X or O on the keyboard.)
