Sooo i playing all day doing quests and i only got lvl 12 for now
any tips?
i doing some sub quests but they give soo litl exp
Some ppl will give up from the game if exp is this low
also what is max lvl now? 100?

Do the crossover event, it gives a lot of exp and nice rewards. That said, there's no secret to levelling with 5x lower exp than originally intended. You just need to grind 5x as hard.

crossover event? what is that? xD
