There are lots of good suggestions here. My first preference would be pico-8 (already mentioned).
But also I can also suggest another interesting option: GB Studio - https://www.gbstudio.dev It's a quick and easy to use drag and drop retro game creator for game boy. It also supports visual scripting.
