balls is a chain reaction game with deck-building mechanics in which you embrace chance and chaos to hit the ever-increasing target score. Start with a small explosion and watch how the reaction extends!A casual roguelite: the game can be played in short runs and does not require a lot of focus.A deck-building game without a deck: the randomness and chaos of the game is directly derived from the bounciness of balls in screen. No decks, no shuffling!Build the perfect combo machine: combine powerful special balls to try and build the perfect combo. Use spawner balls to add more balls to the field, power-up balls to buff nearby balls, or build-up balls that get more powerful the longer the chain reaction goes.
