It is quite a different paradigm from regular web programming - I can remember the mental shift I had to make when I rebuilt my homepage as a clone of the classic lander game (I was actually going to build a clone of an old Amiga game called "Gravity Power", https://www.richardson.co.nz/ https://www.richardson.co.nz/ was as far as I got!) Did you use a game engine? These will often encourage you to follow a particular pattern when writing code. If you didn't, then I'd encourage you to look into entity component systems (which I also used for my homepage). It's quite a light weight pattern and it really lent itself to programming in a game loop (as opposed to say, MVC which fits the request/response cycle of web programming better)
