Slightly confused about this game. It's a sort of middle space between 24xx games and more complex ones, let's say Cortex Prime or Blades in the Dark.
The manual is missing lot of pieces, that, on the contrary, find space in the "SRD", Lumen. GM details, explanation about ranges, scenes etc.
However, the biggest issue is that all the PC progression is too vague, there are no good examples, there are no even little list of new powers of additional mechanics that you can add to the PC. In short, I feel it unconcluded, or so vague that I could choose instead a system with better defined Playbooks, better management of the flow of the game, more suggestions / tables for campaign, missions, faction evolution etc.
I hope it will grow, in the future.
