DIY treehouse update - it's still standing and my 10yo hasn't fallen out

Remember that treehouse post from like 2 months ago? Yeah, I went ahead and did it. Spent like $300 in materials, used a design from this YouTube channel (can't remember the name but search 'simple treehouse build kids').

It's not fancy. It's literally a platform with railings and a rope ladder. But my kid has spent more time in that thing than any toy we've ever bought. He reads up there, hangs out with friends, I let him sleep up there sometimes with like 5 blankets and a flashlight.

Took me a weekend and some help from my neighbor. 10/10 would recommend if you have a decent tree.
