Our debut in the world of VR gaming, back in 2015/2016, happened with qb, an experimental 3D puzzle vr game with the action of a rail-shooter. Over the course of its 25 levels, "qb" introduced players to two boss encounters, each delivering a unique gameplay experience that steadily raised the overall difficulty level. A precision-guided journey unfolds as colored cubes find their mark within matching boxes, while the accumulation of in-game points unlocks a treasure trove of power-ups, all beckoning players to undertake increasingly formidable trials.
