An idea I think would make a good game great is to make Superhot a dual player game. I can't imagine the level of teamwork/blame if the 2 players are not coordinated in their efforts. I can easily see a couple 12 year olds playing the same level for a long time and blaming each other when they fail. I have often seen groups play competitively but if there were 2 folks in the game I am all but certain it would cause harmony or strife.
Know Springboard has the ear of Superhot creators, might want to see what they think. btw - kudos to the arcade build on game, big improvement.
