What was your first language and what did you make with it?
Me... I learned some rudimentary HTML & CSS on Neopets and made a fan site for MTV TRL veejay Jesse Camp, who was my celeb crush at the time. (Bonus points for anyone old enough to remember him.) I think that counts, right?
My first language was ProcessingJS on Khan Academy (which I highly recommend learning if you like making games). The first "real" thing I made was a game called "Boxx", which was a maze/action game where you controlled a square while avoiding red rectangles. Since I was new to programming, there is no actual collision detection for the rectangles. If you want to take a look at it, here's the link: https://www.khanacademy.org/computer-programming/boxxfixed/5596682905059328
