Terminal Phase has also been a great testbed and demo for all our tech. For example, Goblins supports transactionality and time-travel features. But that's hard to understand!
But here's a video of time travel in Terminal Phase! *No* gameplay code changes were made to enable time travel! The game was fully programmed, and then in retrospect @cwebber realized that time travel support was already there, and so simply spent an hour wiring up what was already there to the GUI so users could see.
