They did this stunt at the Olympics opening ceremony.
People have played actually burning pianos (usually old, crap ones) but getting good tunes out of the instrument is not compatible with heating the strings that much, they detune and snap. I think they just used a keyboard built into an otherwise empty piano case with some gasoline.
Exactly what I thought when I saw this. The Celeste soundtrack is so good - I'm not good at platform games but the music kept me going. The story was great too, but I'm not sure I would've stuck with the game if the first steps (see what I did there?) didn't have me humming along.
And I'm also not good at precision jump and runs, it took me several hours climbing the summit, I had to assist in the core and failed utterly on farewell :(
First answer to me is Chris Christodoulou, who did everything for Risk of Rain and Risk of Rain 2. The man knows how to let ambient vibes build to boss music
How has nobody mentioned Chris Christodoulou (Risk of Rain), Studio Pixel (Cave Story), Ben Prunty (FTL, Into the Breach), Christopher Larkin (Hollow Knight), or Andrew Prahlow (Outer Wilds) yet‽
I'm also quite partial to Craig Barnes (Streets of Rogue) and A Shell in the Pit (Full Metal Furies & Chicory).
