Sales quickly averaged ~150$/day and despite that, my parents still wanted me to get a summer job (at McDonald's maybe) like "the other kids". I also had a computer usage quota and was often going over at my friend's house just to cheat the quota :). Looking back at those days, I think they just wanted me to spend more time with my peers. Anyways, I turned out fine!
To conclude, I truly hope your parents are supportive and if they are not, feel free to get in touch with me for advice (can't help with game development though, you are way more advanced than me).
PS: You have a bright future in front of you!
