My biggest complaint is how expensive everything is. There's no gradual build up of price from small to large; it goes straight from large to larger. This wouldn't be an issue if the 'money' were easier to earn, but it's fairly difficult even from the get-go. Still, it's a fun game that I just couldn't get into, partially because of the lack of motivation. If I wasn't going to get more cookies despite travelling so far? I just couldn't do that. Still, I'd love to see a sequel if this issue and some of the others mentioned are resolved!
