About the game
Cal & Bomba is a programming-based puzzle game where players write short command sequences to move through each level, line up a potion-fueled cannon, and take out enemies using a range of explosives. Pitting foes against one another can set off destructive chain-reaction explosions, across a collection of more than 150 brain-teasing levels. Filiokus both developed and published the game in 2025.
