RTG, a game with cryptic name ("ray-traced game", "radioisotope thermoelectric generator"), is a sci-fi puzzle/platformer with very unusual rendering method: CPU based ray-tracing. In time of writing of this text, there's no other game currently available using such method, at least not to my knowledge.
Dive into strange world, where initially, nothing makes sense. Chew through gradually more challenging puzzles and unravel what's going on, piece by piece, by accessing terminals scattered through the game.
Core gameplay of the game is puzzling, but there's also a touch of arcading, all of that intertwined with sci-fi story, resulting in one unusual indie game experience.
