Add some quests that are suited to later stages of the game, with bigger rewards (and thus bigger risks).

Allow multi-touch zooming on the maps, especially the galaxy map.

Combine the buy/sell screens to make trading easier.

It would be better if you could find out what the equipment and upgrades do without having to search the help.

More equipment upgrades, or variants on the existing upgrades (eg the Phased Pulse Laser is 5% better than the regular Pulse Laser).

Gaming on my phone is often interrupted. When I come back to the game, I often remember I just made a killing on Games... but can't remember where I just shipped in from. Would be great to see a history of the last three systems visited. A more detailed Captain's Log showing what I bought and sold in various places could be even better.

Add more quests to the game.

In the pc port of the game, they had custom built ships on certain hi-tech worlds

Since Dark Nova is based on a Palm OS game it would be great to have a WebOS version as well.

It would be good if there were special encounters that only happened rarely. Something like your warp drive failing, or ending up in the wrong system, or meeting someone who later gives you a special mission at a space station.

Fix many of the common bugs reported.

Use palette swaps (AKA change how you colour the ships in) to give variety to the ships you fight against (or buy!).

I would love to be able to change the text of the game so it was all about Firefly. OK could be replaced by Shiny. Pirates would be called Reavers. I bet other people would like to do the same for Star Wars, Star Trek or Babylon 5.

That way, if I find a merc, quest, or just a notable trade route between systems, I can keep it in the log.

Why can't I trade with my friends online when they're at the same system?

Make a build for Windows, Distribute it via Steam, or directly from your site. People will buy it

I'm building a similar but better game, race you to a pc version
