Note that this feedback is based on the build(s) available at the end of the jam.
Overwhelming Odors stands out as one of the more unique submissions this year. Its inhale/exhale based mechanics to attract and repel different smells was unexpected.
There isn't a lot of artwork here, but what there is is fun, and the face feels surprisingly expressive given that only its pupils and nose move.
Unfortunately, noted bugs with win/lose conditions make the game's objective difficult to discern.
Most of the suggestions I would have had are covered in the list of missing features on the game page, so I think you were heading in a good direction. It would be interesting to see how a "wind" mechanic that affected the direction and velocity of all smells would change the flow of the game.
There's an interesting concept at work here, but one that's hampered by a lack of clear objectives and player feedback.
Thanks for submitting and best of luck with the project if you continue development! :D
