About the game

In this retro-inspired 2D platformer with pixel art charm, you’ll join Melissa Tideborne—a bold pirate chasing a childhood memory and the mystery of mermaids. Explore a sunken dungeon filled with deadly traps, lurking creatures and hidden treasures. Your stamina is always draining—every step, swim, and second counts. Will Melissa find the mermaid at the end of the dungeon, or will the siren’s call become her last lullaby?

Melissa Tideborne is a pirate who, when still a child, was saved from a shipwreck from a mythical creature known as mermaid. Even since this moment Melissa became obsessed with mermaids and wanted to meet them, no matter what. After years of searching and going from place to place, whenever there was a small hint about sightings of mermaids, she finally found a clue, a sunken dungeon full of traps and dangers that is said to be a boundary between the human world and the siren's world. Journey together with Captain Tiderborne on a journey inspired on underwater levels from classic retro platformer games. What will Melissa find at the depths of the dungeon? Will she be able to meet the mermaid?

How to activate

Guide for Xbox One

Primary — the game is shared with your own profile

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Now open "Settings" → "General" → "Personalization" → "My home Xbox" and choose "Make this my home Xbox". This is what shares our games with every profile on your console.
3Switch back to your own profile, open "My games & apps" → "Library" and install the game. The internet is only needed for the download.
4Launch the game from your own profile: achievements, saves and progress stay yours, and after the installation the game works offline.

Only one console at a time can be the home Xbox for our account — that is the slot you bought. Please do not change the password, the email or the two-factor settings of the account, or the access will be blocked.

Secondary — you play from our account

1Press the Xbox button, open "Profile & system" → "Add or switch" → "Add new" and sign in with the login and password from your order.
2Open "My games & apps" → "Library", switch to our profile in the top-left corner and install the game.
3Launch the game while our profile stays signed in, and keep the console online: the licence is checked over the internet.
4Use your own profile for everything else — the game stays available as long as our account is signed in on this console.

Secondary costs less, but it needs a permanent internet connection and our account stays signed in on your console.

Activation code

1On the console open "Store" and go to the "Redeem code" section.
2Enter the 25-character code from your order and confirm the activation on your own account.
3After the activation the code is shown as "Used" — but you can reinstall the game from your library at any time.

Notes for Xbox One

Important

Do not change the password or the email of our account, do not disable two-factor authentication and do not activate Primary on several consoles at once — that blocks the access. Details are in the "Warranty" section.

How to play online
