ok here's my list for stuff that would make the game much better.
-weapon reordering (i.e. putting your engine overdrive last)
-volume control (because.... well, it's good.)
-more engine upgrades (specifically more hyperspace engine enhancements, following the same formula as non hyperspace engines. maybe some engines with enhanced manouvering at a cost of top speed)
-some sort of interaction with planets (perhaps specialty items?)
-mining bay enhancements (more efficient storage)
-basic laser enhancements (more damage, more energy usage or faster firing rate, more energy usage)
-make the heat disc actually semi-useful (great idea but its worse than any other weapon atm)
-zoom out (cause when you have a big ship its really hard to see anything - also because the long range laser is pretty much useless)
-larger sectors (just because.... it would be nice and it would compliment a zoom out function)
that's all I have right now.
btw I love this game.
it would be nice if multiplayer would work on flash 9 - I tried downgrading to flash 8 but couldn't connect to the server here and multiplayer still didn't work on your site. I tried adding the application to the safe list on adobe's security settings thing but it didn't work either. still I like it, it reminds me of wing commander: privateer (lol) or a really old game called solar winds. 5/5 for complexity and simplicity combined
