Did you work in a team?
2 people. I was the primary person, I did all the coding art, and most of the experience. Joseph Stierman helped out with getting not as annoying background music.
Overall, this was a very fun experience because I got to create something from scratch and I am very grateful for all the knowledge out there in the community to help out with it. It was a great time!

Was the resolution a challenge?
It was definitely a challenge. I wanted more complex animations but knowing that they'll eat up the whole screen made it very tough.
One particular challenge was not being able to use the out of the box Unity text. It would either come in too high rez (thus, cheating) or be so blocky you couldn't read it. So I had to develop my own system for displaying dynamic text, particular the points and Xmas light pieces remaining. Coming up with the formula to extract the hundreds, tens, and ones spot was way tougher than I thought. But turned out to be a fun exercise as I learned about a lot of Unity math functions I had no idea about, even though I only ended up using one of them. It forced me to research and just kind of buckle down and do it.
Another hurdle was getting more instructions and text on one screen. I ended up getting around this by having two separate information screens, one for points/pieces and the other for selecting a piece. Actually, I think that worked out pretty well.

What did you learn?
I learned a lot in this game jam. Mostly how to deal with low resolution in Unity. But it also forced me to use new techniques and other things I haven't done before on what felt like such a simple concept. I had to descope so much. I think what I really learned was Unity functionality as well as a lesson in making sure to properly scope a big project like this ahead of time. I am so glad I was able to participate in this jam. Thank you so much!
