newt - It was an obvious choice with a "Stealth game" topic of the jam... We've spend almost half of the development time on game lightning with multiple shadowcasters, tilemap objects and blending modes. I was happy to use it!
We're already a team with experience in multiple projects, and everyone had a big motivation for the event, so we've spend all of of time focused on the tasks. Prioritization was the toughest part.
Yes, C2 is an excellent tool, i use it every day! We were only C2 team on the event. A lot of Unity teams, although everybody knew about Construct. When they didn't, we've happily opened the door for them to a brave new world of rapid game development tools!
Last year C2-like tools were not allowed. This year they changed the rules, and allowed all tools. We were surprised on arrival as they handed us rules in which Game Maker, C2, etc were forbidden. It wasn't a show stopper, as we know the way of the Unity, but it did change our plans! Luckily, it was just an error left in from the last year rules.
We even got to the news Here's a google translate link. My team is in the yellow offices!
Here's a timeline of commits during the hackhaton. First few hours we're spent on planning, and it's nicely represented in the graphs and after that we've spent most of the time developing. We've used Google Drive for syncing with artist and sound designer.
