Heya! Thanks for your video, it's always a pleasure for me to see players enjoying the games I make :). Congrats on going over 1 minute, as the game is challenging :).
This game was made in 48h during a Game Jam, so that's why it's a bit "rough" around the edges. I latter refined this same idea to make a more polished SNES game titled "The Last Super", that you can play here:

And to answer your question in the video, yes, "Yo-Yo Shuriken" is an actual SNES homebrew I created back in 2019. It was released in physical edition (cartridge, box & manual). You can play this one here:

Enjoy!
