目前只差两个成就达成全成就，第一个是骷髅行军，扭蛋机已经开完了，骷髅人解锁条件不明。第二个是巨象，目前通关了4次，这个BOSS一次没见过，是属于隐藏BOSS还是关卡BOSS？要如何才能遇到？...

Hi, I'm trying to earn most achievements. I'll never get the lvl 4 boss on hard, that one seems impossible for me, but for the others 3 i'm missing I have high hopes, but would love to get some tips. No, thanks! Is this an event and if so is it in a specific level? Finally gathered I have pink, red, grey and yellow, am I missing a color? Skeleton Army How to unlock this unit, is it a lucky one with buying for 50 coins, or do you get it somewhere else?...

I would really love to be able to switch between the two rows with W/S or arrow up/arrow down.

我已經把目前轉蛋機能轉的東西都轉完了，成就裡面也沒看見也沒看見影子符合的，印象中有用對講機叫出來過，還是說這單位只會在系統隨機卡片裡面有可能出現?

Is it just me, but I can't progress to the next level. I've done it once around to the whale king and when I quit and went back, I stayed in the first level for what seemed like never ending minutes. I don't know if I'm bugged. Tips and advice would be nice....
