You can use the same mod:
And change the file in it to :
ModCrewPointsPerLevel overrides GameSystem
AttributePointsPerLevel 20 //Default 5
Change the 20 into what you want, it only works for leveling up of course.
Attributes is Tactical, helm etc and that does not influence ship size in Drox 2. BaseSkillpoints are what you use to upgrade your ship in Drox 2.
Use at your own risk, I do not know if there are any maximum values you should not go past.
