This is a Twine game with a significant world model. In it, you explore a ship you've crashlanded on which is empty except for an AI named SOLIS.
There are a lot of areas to explore, and you have both an inventory and notes of all important information.
It has puzzles that are honestly complex and can be fairly difficult. The inventory allows for quadratic complexity: you have to be in the right room, and use the right item.
I enjoyed the AI, and felt an attachment to them. The nice thing about IF containing AIs is that the AIs exist in reality, in a sense; the organic characters are just described in words, nothing like their 'true' selves, but the AIs are supposed to be code masquerading as a person and that's what they actually are: code in Twine or Ink or Inform that takes your inputs and reacts to you. It's weird to think about.
Anyway, the game is fairly non-linear and has multiple endings and paths to victory. I think a large chunk of content is the same in each walkthrough, especially conversation, but you can replay those parts with different attitudes.
Navigating back and forth got a bit tedious by the end, but fortunately a new mechanic gets introduced that lets you 'warp' around ((Spoiler - click to show)following the robot).
Overall, I really enjoyed this polished game.
