Because catching fireflies is so tricky, it ought to be possible to "consolidate" firefly catches. If I drag one partially full firefly bottle on top of another, the contents ought to be merged into one of them to the fullest.
For example, I have one bottle with 5/7 and one bottle with 3/7. I drag the latter on top of the former and the result is one bottle with 7/7 and one with 1/7.
Furthermore, there ought to be a cocktail that provides a buff that prevents energy loss when whistling for fireflies—equivalent to the Flaming Humbaba.
The current situation is just way too energy-draining for us poor lower-level glitches! Please give us a little help and at least even the playing ground with the miners for us bog-dwelling laborers!
