Okay, so it feels fast. Overworld movement feels really fast, it feels like I'm at the wrong scale for that map size / ship size. Getting into engagements at first was a little unintuitive (the sonar system?), but was easy enough to get used to. (coloring or tinting the ranges would help too, it's hard to tell how close one should be.
The combat does feel a bit fast and claustrophobic. Maybe it's because we're frigates and PTs. I kept wanting to zoom out more, but that said the sprites seem to already be suffering, they have lost most of their detail at the current scale. If I go into one of the upgrade screens, I can distinctly see all the guns, but when I go into battle, it's squint-fest, and I can't see where guns or torpedo tubes or anything of importance is on a ship. So I can't tell where enemy or friendly guns are aiming, how fast my guns turn, etc. I think I got my engines disabled once? Or was that a bug? One of my sidekicks ran into me about the same time as I was taking damage when it happened.
