Wasn't expecting Salvage Union, but mechs are always a welcome surprise! Really like how you interpreted the title into a rich setting, with interesting setpieces and fun NPCs.
The layout is clean and accessible and the map is well thought-out. The only minor thing I'd prefer is if the Map was the first thing visible, so It is a bit clearer at a glance what is going on, but that is just my preference. This slaps harder than Bright Noa.
