Mappy（僅卡帶）

The cat crooks' dialogue is surprisingly charming for a Famicom cart, and the vintage arcade feel really shines through in the gameplay. My only gripe is the button layout is a bit cramped, but the mouse's stealing-retrieval loop keeps me coming back for more.

The cart loads instantly and the tiny mouse animations are impressively smooth for an 8-bit game. My cat even perked up watching the screen during a play session.

The mouse character controls smoothly, and the cat AI actually puts up a decent challenge. I’ve spent a few evenings on this Famicom cart and it’s a solid arcade port, though the music can get repetitive after a while.
