Here's a brief update on what's in the pipeline. I hope to get it out this week, but it may take a bit longer.
First of all; interaction during simulation. This means you can turn powered things off and on to suit your needs.
This inevitably leads to speculation about scripting possibilities. Like, can you use triggers to start things? Can they enable and disable each other? I won't deny that is a plan, but it won't be in this release.
Then there's a bigger thing: Build Challenges.
The concept here is that you need to build a marble run where the marbles pass certain checkpoints. There are also certain volumes where you will not be allowed to place any pieces.
I hope this will serve as a way to engage those that are not primarily interested in the sandbox experience, but like a challenge. Initially there will only be a few of these, to check the interest, but eventually more will be added and perhaps with added complexity.
Do you have a better name for this than "Build Challenges"? Or a great idea for a puzzle? Then I'd love to hear about it :)
