Don’t listen to people telling you not to post your age on the internet. This is solid work and you did this instead of being stuck in one of the hundreds of +1 dopamine traps in Roblox or yelling at other (often times much younger) kids in Fortnite like many of your peers did.
You did something meaningful, you even waited to share it with the world until version three, and you learned a ton doing it. Well done, dude!
