What SHOULD happen is that Kixeye releases a ByM update on Facebook, checks for bugs, and a couple months later puts it on Kong glitch-free. What ACTUALLY happens is that Kixeye puts the buggy stuff on FB, fixes it there, then puts the buggy stuff here, then fixes it here. It's not a very efficient way to make a game, upsets Kong players, and is quite annoying.
With regards to the champs: Gorgo can pwn at low levels, is okay at mid levels, and isn't too great at higher levels. Fomor is pretty sucky early in the game, gets better as you level, and is awesome in the late game. Drull is all right early on, reaches his peak in the mid-game, and is moderately good at the end-game. [+] if this helped you out.
There's good news and bad news. The good news is that it IS possible to buy the last upgrade, because if you play long enough, you'll overload the 16-bit Flash counter (I think it's 16-bit). The bad news is that you need about $340,282,370,000,000,000,000,000,000,000,000,000 to upgrade before both numbers stop and you can buy it.
I USED to think Facebook had a much better game than Kong. Now Kong is a million times better as I got forced into MR3 on Facebook. Thanks, Kixeye, for the lack of Kong updates! << absolutely zero sarcasm
"You need 1 more resources to upgrade. Buy them and start upgrading NOW for 2 shiny?" So you mean I get 1/2 of a pebble per shiny? SOUNDS LIKE A DEAL! I'LL TAKE IT!
"You need 8 more resources to upgrade. Buy them and start upgrading NOW for 4 shiny?" Nah, I think I'll wait the extra five seconds for my twig snapper to make some more twigs.
