Thanks!! It was one heck of a push towards the end!
I think the biggest thing that helped both of us was planning! We spent Thursday evening brainstorming ideas and searching through our assets, and anything we could find online. We both spent Friday / Saturday getting the mechanics / systems to feel just how we wanted. That spilled over to Sunday morning, but we were able to get it smoothly working so we could focus on designing the level / polish Sunday afternoon!
The two of us have worked together previously on jams, so we had a good system set out, and we both knew what each other's expectations were and how to best support each other!
We used codecks ( https://www.codecks.io/ ) for project management, and Miro (https://miro.com/) for a collaborative whiteboard.
We are so glad you had fun! ♥
