This is my ludum dare 42 game, otherwise known as "Astronauts with Flamethrowers". It was made using an engine that I made in 3 days known as the LDEngine. The most noteable features in the engine are: hardware-accelerated path-traced light baking with bvh generation. reflection-probe rendering and loading using cubemaparrays. (supports potentially hundreds of reflection probes)
