definitely fair. possible solutions i can think of would be to scale the upgrades (like make each purchase more expensive than the last type of scaling. *like more than it already is*) or to reduce the amount of DM gained from stardust (i do want to point out that the DM gained from the planets currently feels a bit low but i can kinda understand the amount given for the amount of planets we have access to.) as for the scaling i think doubling if not tripling the price of their current numbers (first upgrade price shouldnt be changed *like the first purchase one only honestly would only apply to new saves since they would start over* yes this type of change benefits those that already *somehow* managed to buy all the DM upgrades *or those that managed to buy upgrades as the reset is something you are avoiding* but is 1 way i can see it happening) as for the reduction of stardust gains im not really sure the exact method it is (i think its 1 for every 1k stardust) id say add a type of compound scaling to it where to get the next DM you need an increasing amount of stardust (ie first DM is the 1k but the second requires a total of 3k *this means the second one if we dont count the first one was 2k to earn* with the 3rd being 3k after the 2nd and so on so forth) just some ideas. im not knowledgeable on programming so i wouldnt know how to code that but i assume since you already have a game out you have a better idea of it than i would. *tangent/off topic sort of* ironically i have had friends where when i tell them my ideas they are like why didnt i think of that type of thing. it dont happen often that i get such ideas (i think the last time one came to mind was something for warframe *the space ninja game lol*) and even now i cant remember what the idea i had was but they all seemed to have liked my idea sometimes i wish i could program or at least knew what i could do to do such things (yes i know i should do something about that) anyways if i get any ideas of that nature i will definitely give you a heads up.
