Anybody else remember Kutar's Tabipero? It's been years and years since I last played it, but even now, sometimes, my brain just starts playing The Horn Song while I'm trying to do something that consists of long and short...
Here's a random clip from 16 years ago from someone else, if you need it in your brain for any reason:

(Video description: A cartoon cat plays a honking big Swiss horn according to whether a mountain scrolling by in the background is tall or short. Dancing cats and two conductors in tuxes appear to listen and hang out, more and more the better it goes. Flocks of doves congratulate you when it really goes well. Upon fucking up, the cat compresses in defeat. There's about three whole pixels.)
If there's any community on earth that randomly knows some weird Japanese game that was popular about 20 years ago, then surely it's here...
