The mute system is a little confusing. Basically, Twitch auto scans the video for what it thinks might be copyrighted audio, then it mutes that section for you to prevent you from getting a copyright strike. This is all automatic and set to extremely paranoid because when a big wave of copyright enforcement went around a few years ago, that was equally paranoid and ridiculous. People got copyright strikes for 2 second snippets of something you could barely hear in the background. It was bad.

But the auto mute isn’t a strike or even a warning. It’s no authority at all. It’s just a random automated guess at what companies might be looking for when doing their scans. It’s there to protect you in its weird and uncomfortable way.

You can dispute, but that puts the responsibility for any claims on you. You’re waiving the protection. It might be fine, but if it isn’t you suffer the consequences. So generally it’s usually not worth the risk to bother. But a mute is no big deal. It doesn’t hurt you or count against you in any way.

tl;dr: nobody is actually claiming that audio is copyrighted, except some robot scan thought it might be and better safe than sorry.

If you like QfG, you might be interested in Heroine’s Quest: The Herald of Ragnarok on Steam. It was released for free and I imagine that hasn’t changed. But I still ended up donating because I enjoyed it so much.

Random thoughts in no particular order:

Circle of the Moon was actually not made by IGA. It was developed simultaneously by Konami Computer Entertainment Kobe while IGA worked on Harmony of Dissonance in Tokyo. However, to me Circle ironically feels closer to an IGAvania of the two while Harmony feels like IGA was trying to make something partway between Symphony and a classicvania.

Aria and Dawn are generally the best liked portable games, but OoE has a loyal following due to its much higher difficulty more reminiscent of the classic games.

Harmony of Despair is surprisingly enjoyable. Even if you missed the boat, it can still be enjoyed on a PS3 emulator with all the DLC and even online multiplayer. It’s honestly a blast.

There’s also a mobile game called Grimoire of Souls and, for the really obscure stuff, some Japan only Castlevania casino games.

Of the PS2 games, I remember quite enjoying Lament of Innocence and keep meaning to give it another play someday. The other one I forgot completely.

I’m looking forward to Bloodstained 2!

Edit to add one more: there’s a Sega Saturn version of Symphony of the Night where you can play as Maria. It’s Japan only, but a translation patch can be found online.
