It's very glitchy but most of it just visual bugs
For example, anything that isn't within a certain radius of you is at like 3 fps
Or any time you exit a building it glitches out the camera
And recently whenever I start a terrastel raid there's a grafaiai that just sits there in front of you, it doesn't move, doesn't attack, and you can't attack it. It's just weird
Other than that the story is really good, there's a ton of different characters and once you figure out how to upgrade miraidon it gets a lot easier to travel
My main complaint is that they removed a few game mechanics from legends Arceus that I would've preferred to have in violet
For example, being able to throw pokeballs without entering a battle, let's say your pokemon are on low health and you find a really rare Pokemon
You can't sneak behind it and throw a pokeball because they removed that
There's also dodging, however since the pokemon don't attack you it isn't really needed
You can still crouch and hide in the grass but the only benefit of that is you get free attacks if you start a battle, for the first couple turns the pokemon doesn't move
Overall it's a pretty good game even though there's some things I would change without hesitation if I could
