I resolved my current issue regarding locking and unlocking buttons. I am basing my levels on the marks the user got. If they got a score of 25 and above, they will proceed to the next level. Now the problem here is since my quiz is sharing one code with a different JSON file, when the user perfects the score on the first stage, the whole level will unlock which is a no-no. The idea is even they scored perfect, the next stage will be unlocked not the whole level. I tried thinking of ways on how to do it but nothing comes to my mind. Can you help me? please. I really need your help. Thank you.
