interesting concept! there's definitely a solid game here, but the small number of puzzles and lackluster instructions are a bit of a disappointment. some sounds would be nice too! i managed to figure out how it works fairly quickly, but i think it's quite confusing that the "input" and "output" containers are on opposite ends of the screen when you're actually able to put the inputs and outputs anywhere on the collider. it might have been better to make the containers just be part of the tiles you place rather than separate. i did like how there was a little fact about quarks every time you completed a level though, very cute
