There is enough candy in the first area to complete all the available quests, but it is definitely more difficult depending on who you help first.

playing it the first without any help or knowledge about the game make me thing there isn't any candy left in the first part and the money part dose not make any sense the main character say "i need 30$ to pay this" but i have MORE then 30$ like idk what i had before i think it's more like, one one 40$ so that's more then enough to pay it off but no i had to get little more money to pay that off
