Okay, some feedback i got(i played until i got carbon)
Too many submenus unless you are planning to add the entire periodic table, also there is no mechanical difference between 'gases' and 'solids' so i dont see the point of separating them
You are able to click on the whole resource text but you need to click on the name to actually move to their menu
every single technology is just 'unlock something'. Improving collectors or something could be good maybe? Also, having the first two unlocks just be 'unlock the ability to do more research' isnt really fun. Research is too expensive.
Maybe hide energy until you actually get it? Like you did with the starmap?
Whats the point of fusion when you can just manually gather the result after fusing for the first time?
Helium sells for less than hydrogen, dunno if that is intentional
Actually having a tech tree so you can see future technologies could be cool. Also, knowing what the technologies i buy actually do/what they unlock before i purchase them could be helpful in knowing what technology i should buy
In conclusion, not really a fun game right now, but there is potential here
sorry if i was too harsh or didnt play enough
