Hi, picked this up a few days ago and am quite satisfied with my purchase. Was just getting the hang of 0.35 when 0.5 rolls around the corner!
I'm quite enjoying 0.5 and have some feedback. Much of this I've seen already-- more bases (I think a pirate base as well as a tri-tachyon base would be nice, personally), click on map to travel to a location, seeing stats for equipped weapons, etc. In addition to what's been said, I have some more feedback.
First, I think the brawler needs some help. I tried a number of new games, and found that I could get going with every ship but the brawler. It's just too slow for a starter ship-- anything you manage to badly damage without a critical blow will just run away from you. Also, maybe it's just me but it's more of an anti-cruiser frigate that gets destroyed by fighters and frigates. Considering that you start out fighting those, it's a bit of a problem. All that said, I think just a small boost to the top speed (travel and combat) would go a long way to making the ship a more viable starter.
Of the starter ships, I found the brawler was impossible (for me, at least). The support frigate (can't recall the name, it's got a single medium energy and single medium missile) was merely passable. Got lucky in forcing the surrender of a pirate destroyer early on. Lasher and the rest are comparatively easy-- fast and good power. All of them start out rather grindy, though.
On the whole low-tech v. high-tech, the advantage of high tech comes out all the more strong when the campaign map is added. A high tech fleet seems to be faster, more quickly repaired (if only due to less hull), and less supply reliant. This is in addition to them being able to slaughter their low-tech counterparts with their (seemingly, at least) generally longer range weapons, better shields and higher maneuverability.
Second, unless I'm mistaken the ship stock at the station are not currently replenished. It's nice to have the crew/supplies/weapons replenished, but kind of rough having just 1 of each of ships available for sale. Knowing the power of flight decks, my first purchase was a condor. Sadly, that condor got destroyed not too long after (an avoidable death, I admit). Managed to scrounge up the funds for the venture, but now that's it-- apart from a lucky salvage of an enemy carrier, there are no more carriers to buy. Making the resupply convoy replenish ship stocks (or some other convoy) would be quite handy. On the other hand, I suppose having the extremely limited stock reinforces the whole crapsack universe this takes place in. Lose the 1 wasp wing available for sale? Too bad.
Finally, and I suspect this will be handled with by the skill/officer system, but some way to increase our in-system speed would be great. Not only is it annoying to have all the nice prey zip away from you, but also a fleet of any decent size can get pretty darn slow, even if you strap augmented engines to anything and everything. My best fleet has 1 cruiser, 1 destroyer, 3 frigates and 3 fighter wings and gets a top speed of 144. Of those ships, only the cruiser is slow (a venture). I imagine a low-tech fleet would make system travel require a good book on hand.
Now that all that's out of my system, I can finish up by saying that this is looking superb! I'm happy to have invested my 10 bucks in it and look forward to its future while appreciating its present. Thanks for all your work!
Edit: Adding one more ship to my fleet brought it down to 120 top speed. Added two more destroyers, and it's still 120. Is there a minimum fleet speed? Also, I really wish there was a fast carrier out there. I don't care if it's armored with cardboard and has no weapons, I just really want a carrier that doesn't slow down the rest of my fleet!
