Having fun, but combat can be a bit iffy. I find the damage I take goes from nothing to absurd amounts in no time flat, with little clear rhyme or reason. And the health dropped from enemies is inconsistent and often too paltry to help. Plus you have to go and get it, which isn't always feasible. I think I would have preferred a mix of regeneration and pickups, where you regenerate to a certain threshold and have to find pickups to heal further. Keeping track of enemies can be a mess too. They often get lost, and I'm only made aware of their continued presence by the combat encounter music.
The upgrade/crafting system seems poorly thought out too, or at least, when tied into some exploration stuff. I find myself discovering secret caches using levitation, but because the secret caches are in Executive or Maintenance or whatever, I'm often rewarded with materials that have long outlived their use. I can't imagine any players are still trying to craft shatter, the first grip upgrade, or common mods by the time they can levitate. Occasionally you get a designated hidden area with an ability point as a reward, but not often enough.
