After the credits, you’ll see the Japanese word おしまい (oshimai), which often occurs at the end of a Japanese movie. In this game, its hiragana characters appear in the Super Famicom face button colors, albeit in pastel form.
I love TAS puzzle games, especially when the TAS goes overkill with the combos and sending garbage pieces to the opponent at break-neck speed. So satisfying!
If you want to play this on switch, the snes emulator has panel de pon as one of the games. Its just the Japanese version of this game. Its the cover with the anime girl on the front.
