evie’s interrupts tutorial should help you understand how to use interrupts, and what they are useful for.
tbsp’s “Simple GB ASM examples” is a collection of ROMs, each built from a single, fairly short source file. If you found this tutorial too abstract and/or want to get your feet wet, this is a good place to go to!
GB assembly by example, Daid’s collection of code snippets. Consider this a continuation of the tutorial, but without explanations; it’s still useful to peruse them and ask about it, they are overall good quality.

Vi è piaciuto il tutorial o uno dei precedenti? Quanto segue dovrebbe esservi utile per il resto del vostro viaggio!

RGBDS’ online documentation is always useful! Notably, you’ll find an instruction reference and the reference on RGBASM’s syntax and features.
Pan Docs are the reference for all Game Boy hardware. It’s a good idea to consult it if you aare unsure how a register works, or if you’re wondering how to do something.
gb-optables is a more compact instruction table, it becomes more useful when you stop needing the instructions’ descriptions.
