I can recommend PICO-8, if you have access to any windows/osx/linux computer.
It’s a “fantasy console”, a self contained gamedev environment that emulates an 8bit retro console (while using Lua, a popular and modern language), is super user friendly, and allows you to get a satisfying and fast feedback loop when learning to code.
There are many resources to learn it and a lively community
Actually I prefer to develop in TIC-80, but the community is way smaller, and TIC-80 games can’t be played on phones without a keyboard. It’s not a 1:1 alternative, tho I’m glad it exists.
