At first I was a bit confused on what was considered sour, but with limited options I was able to figure it out! Cute game and I enjoy the little critters wanting some delicious jam. If you are looking for a cute little game try this one out :)

Great game! An Undo feature (in addition to the already existing level reset) would be a fantastic addition. There are times where a single button press caused lots of work to need to be redone.
