*spoiler* getting 100% everything does not unlock anything that I can tell. I got every achievement, reaction, and fully researched everything. It is a good game worth playing, just wanted to let people know so they don't get their hopes up.
every single idle game I've played prior to this one has been better designed to keep pulling me back in for more. I can't put my finger on why I'm so apathetic about this one. It just feels like nothing I do when I'm online matters I guess.
