This is the music glitch:https://www.youtube.com/watch?v=RVuiPL_j2cU
And there are also these glitches:https://www.youtube.com/watch?v=lPOG4X94wQ8https://www.youtube.com/watch?v=ohBPCIjCnsghttps://www.youtube.com/watch?v=vwra-3rLrpE
As this altogether really is a lot, so let's have a look at what's important.
The remaining boundary issues:
Completely not worth it, especially considering you said these ones are harder to do. I expect to be that Dragon Mountain one also to be somehow tied into the puzzle logic (related to the falling bridge, I guess). So I'd say it's the best to screw these.
Capsule Monsters feeding:
Also not that important because it doesn't do too much harm - aside from making the CMs some snobbish and obnoxious assholes. I'd say, skip it if it makes too much trouble.
Looks strange, but doesn't do any real harm. So, especially considering that it looks fixing it has the potential to destroy more than it actually fixes, this one can be skipped as well.Lufia report glitch
This one is a bitch because it totally spits on all your effort and invested hours to beat the Ancient Cave. So this should be fixed if possible.Music glitch
This one is annoying because it easily happens and doesn't go away unless you reset. So this one also should be fixed if possible.
Not really a glitch because it just seems like an intentional safety measurement to ensure you always can refill your powers at all. Theoretically, instead of not touching your money at all, the inn keepers at least could take all the remaining money. But that's not really worth it. Let's just call it generosity.
Hook sound glitch:
Somewhat annoying but as it seems easily to cancel, so no real harm. Therefore, this one really isn't important.Ancient Cave creation glitch:
This one is annoying as it can completely screw over your run. Especially annoying, if you found great stuff, but no Providence yet. However, I don't have any savestate for this one.
Arek intro glitch:
I don't care. If anything, it makes Arek even more mysterious, so it's actually not a bad thing, eh?
I'd say screw this one.Ancient Cave chests:
Actually I'm undecided about this one. I say you can look whether you find an error that lets us make conclusions about how actually it was supposed to be. Then we can think about it again. If, however you don't find this kind of error, then let's skip this one, too.
That's all there is about glitches and bugs I think.
