Looks nice (though I always think that shooter + indie do not match).

The explosion of the rocket looks a bit small, the missing texture are not so cool.

A death animation would be cool (even if the screen only turns red, while you sink into the lava.

Two "bolters"?

After you pick up a weapon, they should be removed for a few seconds, including their "light".

And I wouldn't give my user so many possible things to customize in the UI - he might think you were unsure what to do there.


Just my two cents.
