@Ashely, you need to kee vo on. the accessibility mode is that the game works with voiceover.
@Grryf, you can find the boosts in the castle, there is a section for quests which are goals you need to complete for perminant production buffs and the like, and a section for boosts which are temporary bennifits such as %10 sgreater sales prices for ten minutes.
@Slj, I'm a bit confused about the trouble your having with the game, since for me, I just flick to the play button and it worked fine, I didn't even need to enable accessibility mode since I think opening the ap with vo enabled it by default anyway.
You might try closing with the ap switcher and then reopening withvo.
I'm afraid the vo curser bounce issue is one which is becoming a little urcsome. It seems to happen most often when flicking through a long list or double tapping in places where there are several options, eg, I just had quite a task enabling the salesman boost since whenever I double tapped on the button I was bounced elsewhere.
I haven't seen this happen to me in the city or princess screens yet, but I can see that happening if the screens get more information, eg, if I had lots of different products in storage to sell.
Hopefully though these are the sorts of bugs that can be squashed, I can say the game is certainly addictive thus far.
