The explanation to "Y NO FUR COLORS MELI TIG U SUK". By Melibuelle on the official forums. Link here:
Hi guys
As some of you asked for more communication from the staff, I am making this topic today to explain why the fur colors didn't come out yet, and why we can't answer you when they're gonna come.
We did implement the colors back in June, I made all the mice sprites color-izable, and Tig made it so we can change color dynamically without making a sprite for every color. We did run a lot of tests to see if it was viable, if the performances were okay etc.
We realized it led to a massive waiting from the players, the feature being the most expected by far. I can't count the number of private messages in my forum inbox asking for a special color.
Though, we didn't release it to the players. Why ?
Because we need to eat.
Let me explain here. Our goal was to propose to the players a few colors that you can buy with cheese (with a bit high amount to keep it rare), and more colors that you could pay for. Yes, that's right, microtransactions speaking here. BUT, we wouldn't sell those colors : we would leave you choose the price. Like, some kind of donation in game, but you would get a fur color to thank you. From 0.2$ to how much you want, and you would get a color.
We also intended to make some colors event-only, that you could win throught tribe wars, contests and so on.
But, we're facing a technic issue. We don't find a suitable way to pay in-game payments, as we know we would need many payment methods, like Paypal, Credit Card, Phone etc. Nothing quite really suits us right now. Plus, the company isn't quite fully registered yet, and while we've blocked the ads payments on the accounts in waiting for our company bank account, we won't start the microtransactions until we have a proper professionnal bank account.
So that's it, that's why we don't release the fur colors yet : because we've already put a lot of money into making this company (I made some counting this morning and realized I've already pulled more than 3500$ in it myself, with no revenue since May), and while ads are doing okay for the servers, we still need an additionnal income to support us and the future Community Manager that we're hiring.
That's also why we've removed the donation button, we want the players to get something back for their donation. We might come up with more exclusive items for donators in a close future, but we thought it would be a good start.
We're very sorry we've been so secret about it for so long. We're going to try to communicate more from now, about updates, thoughts, reasons etc.

is their still a chance that there will be fur colors to everyone?
Fur colors are definitely coming. Fur colors will be available to everyone, but the ones that are donating will get other fur colors not similar to the ones obtained by events for everyone.
