The Team

Rombo was just a little idea and some sketches by Lauren in 2014, when they had too much time on their hands. When Dave and Lauren started talking shop, they realized they had complimentary skillsets and started to build Rombo in 2023, making huge progress towards a first playable milestone. This game as at the heart of Black Heart Games development. We might make detours to chase down a game jam or proof of concept (see Rat’s Revenge and PlinkIdle), but Rombo is our primary focus.
