Hi hallowclave. Thanks for playing and taking the time to provide such awesome feedback. I will try to address all your points, please forgive me if I miss something!
Firefox on mac working...
Thats weird... but good news I guess. I don't know what's up with firefox and I've spent so much time trying to get it to work. I've almost given up at this point...
Digging Direction
We're planning on completely reworking how these mechanics work so that you click on a block to dig it out. We might not get to this super super soon but it is in the plans.
Cosmetics
Definitely on our radar to add cosmetics AND character customization when you start the game.
Fossil Ratings
This is a bit confusing. There are individual ratings for the fossils and then an overall rating for the exhibits. If you pick up a gold fossil and you already have a bronze fossil in an exhibit, it will automatically replace that fossil with the higher quality one BUT that doesn't necessarily mean your exhibit quality will go up.
The exhibit quality only goes up if enough fossils are of a high quality.
We'll work on making this clearer :-)
Duplicate Fossils
We have thought about duplicate fossils. But until you can do something with them it would just confuse the player. In future we might allow the player to get duplicate fossils and sell/trade them with other paleontologists. We're thinking about how to deal with this...
Brush-the-dirt-off-of-the-fossil minigame
Totally on our radar and in our plans! Great minds think alike. We're just still working on figuring out what kind of mechanics we want to add here and how to make it fun. We might make bones degrade slowly over time and then you have to maintain them? Something like this is coming soon though!
Broken Hotkey on mac
Sorry... I'll add an alternate key for mac in the next update I just forgot for the previous one :-(
Gigantopithecus
Looks awesome!!! We've got such a humungous backlog of dinosaurs and fossils we want to add and it takes quite a while (about 4 days of hard work) to add each dino... so we'll try our best to add Gigantopithecus.
Thanks for playing!
