That makes sense.
And you're welcome. I understand the jam deadline constraint - that's always the enemy in the end. And I'm glad to hear you wanted explosions. We all do. We all do.
And the snapshot idea is genius, or even (yeah I know this a lot of work) a full replay system. It would be cool to make like gif, and then be able to upload to imgur or something.
You're on the right track, keep it up (if you want, I'm sure you have a main project to focus on, so good luck on that as well.)
