Dolpen

Treasure hunting as a dolphin

Dolpen is a PC underwater treasure-hunting game where you play as a dolphin. Search the ocean for treasure chests and collect as many as you can before your diving time runs out. Each chest contains useful items, but when time expires, you lose some of the chests you’ve gathered.

Catch fish and upgrade

Catch sea creatures to earn experience points, then spend those points to improve your dolphin. Upgrades let you swim faster, stay underwater longer, and unlock abilities that help with exploration.
