Read full description

Take control of a quirky little submarine on a peaceful underwater journey, until the sea creatures start swarming! In Mellow Submarine, your mission is simple: dodge everything and stay alive as long as you can. But watch out: not all power-ups are helpful. Some bring blessings... others, chaos. Features: Fast-paced dodging gameplay: Reflexes are your best friend. Dynamic sea life: Dodge jellyfish, sharks, and other unpredictable creatures. Random power-ups: Gain score boosts, shields—or get cursed with wacky debuffs. Not so-chill soundtrack: Keep your cool with soothing underwater beats (until it gets intense!).
