SwitchBlade (itch)

In SwitchBlade, you are tasked with fighting your doppelganger in a 1v1 brawl to the death. You and your opponent find yourselves in a special arena, with the power to switch between it and a noir mirror world. Take advantage of the differences between the mirror world and our world to weave between the platforms and catch your opponent off guard. Switch sides to gain the advantage and avoid attacks, or to get the high ground and unleash your own onslaught.
