Beautiful little game, the emotions mechanic is very smart and I like how the game has a deeper theme, but the story gives a cute spin to it. The sound design is great and the characters are adorable - I can see myself spending more hours in a world like this if you decide to polish it some more!
I think the game would benefit from a small tutorial (I still don't know what happiness does other than the double jump, which took me a while to figure out. Smart detail!). Also, it needs some ways to inform their player of their progress or to nudge them in a certain direction (like highlighting the NPCs, letting them know they collected the honey and should head back to Sadness, have finished cleaning the oven etc).
What wasn't clear to me from a narrative point of view, is the story of the NPCs. According to the story, people got polarized to a single emotion... yet their names suggest that the people are the emotions themselves. Maybe this gets clearer later on, but at first it seems like you're telling two different stories.
Finally, this may seem like too much of a nitpick but.. making bees the enemies you kill and stealing their honey might come off the wrong way. I'd consider swapping the bees with actual monsters.
Overall, this is a great first step. Dig deeper and I'm sure you'll find lots of ways to make it impactful and memorable!
