Howdy!
The last few weeks have been challenging from a technical perspective, and I've decided to delay updates to the Demo until the first full version of the Ship Combat stuff is done. I think it's slowly developing into something impressive (Especially for a Twine game), so I hope it'll be worth the wait once it's a feature of both versions.
I'm admittedly getting super bad at putting out planet swaps at the start of each month, so I will likely change how the Demo works in the near future (Either automating the swaps, or just releasing a stripped down version of all planets, all the time).
Thank you for your patience!
