This is an educational platformer for the NES where Mario must recover stolen art. You travel through time in a submarine to different historical periods. It's a strange, slow-paced curiosity, more of a digital museum tour than a traditional Mario game.
The gameplay is a chill adventure focused on exploration and simple puzzles. The core unique mechanic involves finding and placing historical artifacts in their correct time periods to progress. It's an odd but interesting mix, perfect for a relaxed, curious playthrough.
