Lovely illustrations and UI work. Exceptionally impressive that the engine was built using HTML, something I've failed at numerous times in my own endeavors. The music is all delightful as well.
I initially found myself fairly confused at the beginning, like I felt there should have been more of an explanation about who the player character is, what their goals are, and what their world is like. It led me to not understand the potential outcomes of my choices until I had a firmer grip on the premise.
One small gripe about the engine/UI is at the tribe council screen, I originally didn't understand to click the 'give nectar' button because the tribe images highlighted on mouse hover, so I assumed clicking the picture was the actual 'button' itself.
I felt the dialogs through the day could have been formatted a little differently. I usually had to re-read portions where a character was speaking, finding some trouble in discerning when lines were spoken by other characters or the player character.
It wasn't until day 4 when I realized how the hybridation screen worked, and that I had to click on the buttons outside of the center to bring up new flowers to research. My own error and lack of understanding, but maybe the un-researched buttons could be highlighted or have some kind of visual association that would encourage you to click on them.
I may have found a bit of a bug on day 4 where I was able to make a selection that supposedly subtracted two nectar, but I only had one at that moment.
The plague theme and status report at the end of the day gave me very "Pathologic" vibes, so extra kudos to you, regardless of it was intentional or not :)
Overall, this is a super impressive submission with a great usage of the themes. Everything felt very cohesive. The art, story, and audio all felt like they belonged with each other. I was always super nice to the dryad, wanting her to grow big and strong.
