The game is a fun, physics-based puzzle platformer. Fall Flat Battle takes place in floating, dreamlike environments filled with interactive items and obstacles. You can go through different dreamscapes, solve physics puzzles, and complete tasks by interacting with your surroundings, such as running into doors, pushing buttons, stacking things, hopping over small gaps, pulling levers, triggering switches, etc.
The game contains various stages, each with its own set of themes and locations to explore, such as a mansion, a train, a city, a factory, a forest, a mountain, and more.
Playing through each level of the game will test your mettle against different enemies and obstacles. You have to direct the character's movements and interact with a plethora of ambient elements to figure out the riddle. To get past challenges, you can use your climbing, pushing, pulling, swinging, or stacking skills. You will need to make use of your creative problem-solving skills to get to the exit door; once you are there, you will be able to pass through it and move on to the next level.
The game lets you freely explore the region and approach stages in various ways, rather than following a predetermined path. The riddles could have multiple answers; use your creativity, work alone, and engage in autonomous exploration to discover one.
Although the game begins with a fairly easy level of difficulty, it gradually grows more challenging. Later stages add complexity to their puzzles, needing more inventiveness, problem-solving, time, and effort to finish.
