This is a puzzle game based on the Nintendo character Mario. The Princess has invited Mario and Luigi to a picnic in the Mushroom Kingdom. But when the Mario Brothers arrive, they learn that King Bowser Koopa is making over the kingdom into his personal resort and the princess has been kidnapped, again.
Mario and Luigi must stop him and rescue the princess by closing doors in the hotels.
Most hotel stages have 10 levels, other stages have less, others more. You close doors by pressing button 2. Enemies will come through some doors and will try to open doors to prevent you from succeeding. You can jump on some enemies by pressing button 1.
Behind some doors, you will find a mushroom that will allow you to take a hit without dying. If you already got a mushroom, you will find a fire flower that will allow you to shoot fireballs by pressing buttons 1 & 2 simultaneously. This will take out some enemies easier and other enemies can only be defeated with the fireball.
When you reach the top level of your current hotel, you will need to close the doors here while avoiding one of the Koopalings. Once you succeed, there will be an animated FMV cutscene then it is off to the next hotel (stage).
All the stages are plays on real hotels, like Morton's WoodDoor-Hysteria Hotel, Roy's HardBrick Hotel, Lemmy's High-ate Regency Hotel, Bowser's Seizures Palace Hotel, etc.
The reason Nintendo licensed their Mario characters to Phillips Interactive was because Phillips and Nintendo were co-creating a CD-ROM add-on for the SNES. The contract between them allowed Phillips to create games with the Mario and Zelda characters. Although Nintendo never released a CD-ROM add-on for SNES, they did have the legal contract with Phillips, so Phillips was able to create three Zelda-based games and one Mario-based game.
