Sanrio Carnival 2 is one of those weird little Game Boy gems that never left Japan—which is a shame, because it’s a surprisingly solid puzzle game with that classic Sanrio charm. You’ve got Hello Kitty, My Melody, and the gang dropping onto a grid, and you’re matching them up to clear rows before they pile up too high. It’s like a cuter, slightly chaotic version of Tetris.

The controls are simple (just move and rotate), but the real fun comes from the way the Sanrio characters bounce around with their own little animations. The music’s got that early ‘90s Game Boy chiptune energy too—catchy in a way that’ll stick in your head longer than you’d expect. If you’re into retro puzzle games or just love Sanrio’s aesthetic, this one’s a neat little time capsule.
