I remember seeing this game in Spring Thing years ago and didn't play it because I wasn't familiar with the games it was inspired by.
But I thought I'd try it anyway just now, and it worked fine as a standalone piece.
It's a mostly-linear twine story about a guy named Nigel and his space-traveling alien friend. The two of you go together to a mysterious asteroid where you encounter a variety of aliens.
There is a long lead-up of linear story followed by a more exploratory section.
The writing was interesting enough to hold my attention, and I felt like I had real agency in the choice-based parts. This doesn't look like it was ever finished, but the part I've played is fun.
