About the Game

A roguelike deckbuilder, about flipping coins to cross the Rivers of Hades.

Every "card" is a coin that can land heads or tails (usually), granting an afterlife... or a swift end in the dark waters.

Let's Play a Game of Wunder!

Inspired by Balatro & Slay the Spire, you collect coins and flip them in battles of chance against the Ferryman.

You play by drawing 7 coins from your deck, rearranging and then flipping them all at once. With strategic planning and more than a little luck, they can trigger & reflip each other; destroying the target score, if not... well, what goes up must come down.

Features

  • Journey through the Rivers of the Underworld, from Styx to Phlegethon; each river will test you in different ways. Cross to the other side and try your luck in the endless mode, Asphodel.

  • Build a strategy using unique Coins and Talismans. All the Coins are based on figures throughout Greek mythology, each with their own unique risk / reward mechanics that can synergise or disrupt each other.

  • Upgrade the heads, tails or both sides of each coin in order to create a balanced deck, or put everything on one coin and pray to the gods that it lands heads and breaks the game.

  • Many decks in the form of different classes, each with their own game-changing abilities.
