Thanks for playing.
A lot of your feedback is similar to feedback from others who played it during the jam. I'm currently working on improving it and have already resolved most of the bugs and implemented most of the simple improvements, but not updated it here yet.
I'm currently thinking about how to expand the game with art, objects, more characters, possibly a score board and high score system. I'm also thinking of adding in a "village" with other characters that can be interacted with, and an endless mode. I understand the point of not having an ambitious final goal, but at the moment the only goal is to collect enough jellies to meet the daily quota which isn't very challenging, so I'm not really sure how to expand on this in a way that would keep the original goal.
Audio is really not my strong suit at the moment and I am trying to improve on this, but the time I have to really focus on it is limited.
