I've just published a postmortem devlog for my entry. Unfortunately my submission was not very well optimised, and missed the mark on a key rubric (haptics). In my post I've discussed how I at least doubled my framerate, and my intended approach to adding more haptics and interactive elements to the world. I'll wait until after the voting period to release these updates but they will include using hand poses to invite butterflies to land on your hand as well as flowers that react to player touch in a more convincing way :)
