Thanks for the comment.
Duplicating weapon stats is a good idea, I will think about implementing it.
The description for the reactor parts is not yet ready due to the complexity of their miscalculations. The first part gives a power boost parameter and increases heating. The second part increases this parameter and increases the maximum temperature. And the third increases the cooling and power as a percentage of the parameter from the first part.
Saving will not be soon. f5 and f9 were used for debugging in older versions and have not been removed. There is still the leader mech movement on the arrows and f6 for partial invulnerability.
