Not assembly? Amateurs.
C Programming Language
Welcome to the C community!
C is quirky, flawed, and an enormous success.
... When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn't developed under the advice of a worldwide crowd.
... The only way to learn a new programming language is by writing programs in it.

Not Manually Flipping Bits? Amateurs
I use butterflies
I wholeheartedly recommend everyone try doing a Game Boy game from scratch. The ROM will run on anything. GBDK is accommodating and forgiving. If all you want is some sprites atop a scrolling background, the only obstacle will be remembering to put data into CHR-RAM, so your sprites and background aren't invisible.
Oh they're still using C under the hood whether rustaceans like it or not - games need performance.
More likely c++
Also rust would give you similar performance and there are game frameworks for it.
