I'm 15 and I just launched LoveYourLanding
I'm in the mid developing my web tool that analyses hype for video games.
At the very first I started working on it for my own likes and after a year of work or so, it slowly become something I can show to public.
Basically it aggregates data from multiple sources (like twitch and steam) and analyses the current hype for the game.
Happy to hear your feedbacks!
