Practicing is a creative skill. Practice really is a terrible word for it, because it suggests s dumb, inefficient way to learn. Research, investigation, pushing boundaries get at the idea better.
Adults have a hard time learning new things largely because beginner's mind feels so alien and tedious to them. A kid is shocked to discover how great that first E major chord sounds, and experiences like that are motivating.
It's easy for beginners to find low hanging fruit, because there's so much of it. But if you periodically step back to map the terrain, there's always something within your reach that will feel satisfying when you get it, no matter how much you already know. How is my rhythm? Can I play to a click? Do I recognize chords as fast as I want? Can I play doublestops? Can I do funk? Counterpoint? Odd time signatures? How are my biomechanics? Bichords (that's two chords at the same time)? Symmetric scales? Microtones (instrument permitting)? Can I convey peace? Excitement? Morose? Military? Exultant? Afraid? Call and response with someone else? Between my two hands? Within one hand?
Also it's helpful to avoid the goal of "dominating" such targets. I will never dominate "rhythm". It's too big. But I'll keep improving.
For those reasons, I'm skeptical any game will be good for very long. It doesn't know what you need. But that said, there is software that can teach you a lot. Practica Musica was a mind-expanding experience for me.
