There are these https://en.wikipedia.org/wiki/BASIC_Stamp
Personally though I think even C is too high level for the AVR-8 and like coding assembly with the caveat that there are two ways "up" if you outgrow AVR-8, one route is to go to ARM or ESP32 in which case your C is portable, the other is to go to an FPGA with a soft AVR-8 and talk about playing on hard mode.
So yes... BASIC is absolutely a contender for small systems. But so are MicroLisp and FORTH. Personally, I prefer Lisp, but completely agree Lisp's learning curve is waaay steeper than BASIC's. Same for FORTH.
