The lack of jump button conforms me, telling me that the terror that evil that were the jump puzzles of Marathon, shall remain sealed.
With the shielded enemies I wasn't 100% sure if I am actually hitting them and do damage and they are just really tanky for my beginner weapon, or they are deflecting with their shields. I was playing on Normal.
Beginner pistol (Damocles I think?) loads back the charges really slow, spent most of the fight with the shielded enemies running around waiting for it to recharge. Only after I got to the first rifle, I realized you can reload it as normal. Life was easier after that. The way ammo is handled early pleases the gun nuts around the world.
Having some sound cue when healing instead of the text message would be an improvement. I think maps to the terminals have been added lately? Those are good. Some other guidance wouldn't be remiss later, on the "I'll shot the Deputy Too" level I've got completely turned around, just going in circles among the corpses of my enemy. Then again, maybe this is in line with the Marathon spirit.
