Me too! So many things were last minute though. 2 hours before the deadline I had only one empty level and could only place the apple - so... yeah, I just scrambled together the best features I had created and tried to make some quick challenges out of those exact features. I'd have loved to do more with it though. Maybe next year when I have more experience and don't have to research how to do things in the middle of a jam!
EDIT: My main idea with level 3 was to add a break where you could spam pins to have a satisfying feeling and also explore the randomness that goes in peggle - and not just make it a super short physics puzzle game. And level 4 was supposed to be hard, but that was negated with the bug of pins persisting through levels that didn't get fixed last minute.. if I had more time I'd have "followed the fun" more and found more interesting levels with new mechanics for sure
