At this point in the game credits, aside from buying health refills, are useless. I have no need for the millions of credits I’ve accumulated and it’s frustrating.
Even if there was an exorbitant conversion rate of say 10million credits for 1 sun it would still be a reasonable option to consider.
The alternative would be to improve the facilities in game. After every facility is level 7, that’s it. The is no need for credits. You are done spending them. Game over.
If facilities were improved I think there could be additional levels, additional directions/factions, and possibly new facilities/items/characters would appear based on the worlds you have visited. There is a lot of potential for expansion.
Thoughts to this topic are welcome and I hope to see the developers listen to their gamers.
