Splatoon ~ Early Rainmaker Mode in Version 1.0.0 - Kelp Dome

Upon using the Rainmaker, you stop being able to swim or attempt to use it again until you respawn. The game crashes at the results screen for reasons I'm not sure of.
Though Ranked modes weren't in the game at launch, they were all varying degrees of functional regardless in the files. Using debug functions, one can forcefully load these early versions of the modes offline to test them.
