I don't know about everyone else, but I definitely found multi-color impossible to be a lot easier than mono color, you can determine which generators are supposed to link where much more easily in the multi color maps than the mono color, which takes a minute to figure out where everything is supposed to link to
Well, Super Hexagon is a LOT easier, with no wall deaths, more movement choices (mouse, gamepad), and less lag in the controls.
Still, got the badge in 5 minutes or so.
