Overall this seems like a really solid and interesting system! It streamlines some things compared to a system like D&D which is nice. I really like the Schrödinger’s Gear mechanic - I think that’s a clever way to allow for some variability and player-led storytelling throughout. I’ve played some Scum & Villainy and they have some similar mechanics, and that type of stuff is always fun.
I think it would be awesome if you were able to work with an artist to add some images, as I love a source book with cool pictures :) Also, unless I missed something, I did not see any character classes (although I did see reference to a pilot and gunner, so a little unsure). Speaking personally, I love systems with character classes because I find figuring out your class to be one of the most exciting parts of an early campaign. So potentially could always add something like that in the future?
