This game has such a cute concept! I don't fully understand under what conditions the companions join or the point of the different ammo types, but it felt like a great idea for a bullet hell 👌
Thank you for your feedback. More powerful weapons consume faster your nectar bar, having a higher impact on enemy stats such as health, speed, etc. The other bees join you once you've cleared the first two areas (any), but you've got to go back to your hive!
