EotM's gameplay is too centered on tricks, like dropping the fly C with PU bouncers (plus, sometimes the carrot remains in the pit and is hard/risky to get).
In semi you can do a whole lot without the tricks, but in EotM you practically lose without them.
EotM is also small and symmetric and has many tubes, and at any given time you have much fewer options for your next move than you would in (for instance) semi.

Sure EotM is a good level, but it's recent popularity is ridiculous.
