Same with me. Started at 14 and now I'm 18. I've left the game about three times but I couldn't let go entirely. I've had a bunch of good memories and a handful of bad ones but I have never regretted coming back and won't ever regret it; even if there's a Robloxian infestation.
I now have the biggest door collection in Cubic Castles, having amassed a current 670 doorways in one realm. If anyone has a portal/doorway they'd like to get off their hands, or could do without, please, hit me up. I'm begging you.
