The game is great! It's a 10/10 for me.
I would like to be able to sell cobalt and vermillion bars, the same way like the other bars. A gatcha machine related achievement would also be good.
I am currently working on getting all the sigils 4/10.
Thanks for playing! I'm really glad you enjoyed it!
The ability to sell Farfields resources will be added in the next minor update. As for the gacha machine, I plan to have some special rewards for it. The current rewards are placeholders, so I'll probably hold off on adding gacha-related achievements for now.
Good luck unlocking all the sigils! Nix is definitely one of the tougher ones.
