installation was painless, launch quick, looks good.
I could live without the "buy stuff" splashscreen.
5 min:
Hexes! Heaven.
learning curve minimal (I've played SC before)
Good graphics - in particular the frontline graphics, great. Easy to see what's going on (middle-aged eyes, but with reading glasses)
30 min:
suggestions:
let's have the mini-map show territory - axis / allied / neutral
can't find a way to do extended movement with "forced march", so movement is slow
in the highest map view, no blinking markers for units that can still act / haven't acted - update, sometimes they blink.
Upgradable and reinforcable units show even when they can’t be upgraded / reinforced because of movement or proximity.
Good stuff:
more good graphics. The spotting range indications are good, "stormy seas" look good, etc.
1 hour:
scrolling by dragging is laggy, compared to smooth edge-of-screen scrolling
I'd still like to select multiple units (perhaps by lasso) and upgrade / reinforce en masse
Apparently... no stacking

teleportation ocean hexes are still there. Pah. Just allow a unit, any unit, to have an "end point for movement" set, then the AI can move it each turn until counter-manded or the destination reached. Simplifies gameplay while being much more realistic than teleporting straight past a screen of subs etc.
Sea movement is good. Watching the wiggle on east-west movement is amusing

rain graphics are good.
music is okay. sound effects the same- most or all(?) are recycled
it's performing well enough, could be faster in calculating turns (e.g., supply).
Research screen is good, quick to see. Limit of two points seems okay.
It's working cleanly on my two-screen system.
Invading Norway auto-magically is fine by me,and has a historical feel to it.
Auto-retreat of sea vessels is good. Was it there before, outside of subs?
