Thanks for taking the time and effort to give us additional feedback.
In the dev version of the game in my PC it is possible to outrun the enemies, you just can't do it without dodging a bit (+ oxygen management).
The extractor wasn't fully functional in the GameJam upload, apologies for the confusion. It is supposed to extract metals from asteroids in order to repair your ship. In the dev version it can already do that but I still need to work on the spawn rate of extractable asteroids and their variation with difficulty (harder to find in higher difficulties).
As for the reload and ammo display for both the machinegun and missile, I'm thinking of making their icons be filled with color clockwise and deplete as you spend ammo, another option would be making an external gauge or a (amount/maxAmount) display that changes to (reloading.../maxAmount).
The UI artist will be working on a better controls instruction panel as soon as he has some free time from work.
When these changes are ready we are thinking of uploading the new version to the game's page, since the Jam's version cannot be altered(I think).
I didn't really understand what you meant by changing velocity more easily, is it having a higher acceleration or maxSpeed?
Again, thanks for taking the time to share your opinion.
