Love the idea of trying to evaluate some chaotic situation. Also you strike the perfect ballance of chaoticness, where player can still sort of guess the right answer, but still need to pay a lot of attention.
Could be interesting if you must write exact number for each score. Then it will coun't how far you've guessed. Then you could play for better highscore.
The presentation could be more polished, but this is a game jam submision, so there isn't time to make everything perfect.
