Thanks for checking it out!
Yeah, if you have a massive base, the repair work can start getting overwhelming - so I should probably think of some way to help make it a tad easier.
Next update: I usually try to get updates out every 2 weeks or so, as my free-time allows :)
Music in-game: yes, it definitely needs some.
Suit upgrades: been thinking about upgrades overall recently (base modules, suit, etc) - I probably wont be getting to them super soon, but in general it seems like it'd be a good/logical feature to add.
Cheers!
