As someone who played the hell out of idle loops and terraformental great game, what I miss that these two had is infinite speed, altough this mastery system works nicely too, feels more realistic that each action gives different mastery rewards
I know, hence why I praised your idea of adding different mastery rewards such as more batteries per scan.
I just miss each execution giving improvements, in this idle you complete an action X times and get rewarded, whereas in terraformental, idle loops and others you always get some improvement, even if diminishing, per completion.
Of course those games are balanced around actions being able to be completed infinite times per loop and/or multipaths
Dunno, don't think your game needs it but I would not see it wrongly
