I tested around for quite a while now on a scratchpad. But I think the different systems don't work together.
Turning just does not work well with hexes.
Oh we've got conclusive proof from decades of wargames that turning works just fine with hexes.
What's making it difficult right now is that the UI is clearly in very early stages and that we've got multi-hex units.
Here's a couple of things that would make it much easier:
An indicator that tells you which hex is the center hex of the ship during the movement destination selection process.
A large indicator (I'd put it right over the ship health indicator in the center bottom, or next to the ship name in the turn order list) which tells you exactly how many movement points you've got left and if you've still got a free turn (which personally, I'm not too hot on having anyway but that's just me). Think "MP 4/5 Free Turn 0".
Just that alone would make it much easier to handle movement.
I've already posted my ideas for making control easier earlier in the thread (a 2-click system for movement and facing, overlaying valid facings after the first click before confirming the movement and facing, overlaying firing arcs after the first click before confirming movement and facing).
Although I'll add that WASD for camera movement would be really nice - it's become sort of the standard even for 4X and strategy games, and it just makes sense.
Now that's movement and control, here's some basic UI stuff I've noticed:
The ship status indicator, while awesome is probably not enough on it's own. It's great if you want detail, but if it remains the only way to get information on enemy ships it'll slow play down quite a lot.
I'd love to see shield indicators in the play area when you mouse over a ship (enemy and friendly). They don't necessarily need numbers - coloured facings (the usual green-to-red-to-non-existant would work - although if you wanna be colour-blind friendly make it thickness as well) would work just fine for a quick overview.
Maybe as a toggle like firing arcs if you want to see them for every ship at once.
"Does this enemy ship have shields on this
side?" Hover mouse over it, see coloured facings/thickness of facings and immediately know where the shields are weak. This would be something that is much faster (but less precise) than looking at the ship status readout - which requires you to think about where "front" is for an enemy ship that's most likely not facing "north".
