Built a treehouse with my 6yo and it's actually not falling apart

So I promised my son a treehouse last summer and finally got around to it this past weekend. Grabbed some 2x8s from Home Depot, watched like 50 YouTube videos on safety, and we spent Saturday afternoon hammering nails. Kid was so proud helping me measure and hand me tools. Sunday we added a rope ladder and a little pulley system. It's not fancy but man, seeing him climb up there and yell that it's the coolest thing ever made all those YouTube rabbit holes worth it. Anyone else build one of these? Pretty scared of heights myself but I stayed up there the whole time for safety.
