Pros
Pro Mechanically deep
Through simple in-game interactions, nuanced techniques have emerged that are fun and challenging to master. The package you need to deliver can hit switches, collect jems, and become a makeshift platform - even in midair! Items can be thrown down to boost you up, thrown down and caught repeatedly to travel across hazards, juggled overhead, and more! Input Switches can even add area-specific functionality to any button, including Use Powerup, regardless of whether you have an actual powerup. That's just scratching the surface...
Pro Effective level promotion
New levels go into the Marketing Department, where those that receive the most Exposure Bucks (via players' and creators'-own tips) rise to the top. Once enough unique players try a level, it graduates to the Tower, where players can find it through tags and other criteria. Exposure Bucks are earned purely by playing others' levels, and playing levels in the M.D. nets you twice the amount, thus the system encourages builders to support each other's latest and greatest work.
