Dropper

THE ONLY WAY OUT IS DOWN
Twenty of you are standing on a platform with a hole in the middle of it. Race to the bottom, avoiding hazards. Or you reset from the top! Finish the round as the victor, to earn cosmetics and emotes to flex on your buddies.

FALLING IS A SKILL
You are never just falling. You steer the entire way down. Learning the hazards and memorizing the seed. Everyone has the same job, but you have the chance to be the best. Show off your skills on multiple modes, and trillions of generated seeds.

GAME MODES
'Race' drops the lobby into a full tower on a three-second countdown, granting the victory to a single winner!
'Infinite Fall' has no bottom. The tower keeps building itself under you for as long as you keep falling, and the only thing anyone cares about is the depth number. Infinite fall has a daily seed that resets globally. 

NOBODY MEMORISES THIS TOWER
Every course is built from a seed at whichever of five difficulties the host is feeling, so "I've played this one" is a thing nobody gets to say. And if the tower you drew is genuinely miserable, call a vote, and have it reset for the round.
Trillions of possible seeds.
THE PART BETWEEN THE FALLING
Lobbies hold twenty, friends join straight through Steam, and bots fill the empty slots so three people still get a race. Victors are back in the lobby spending their earnings at the cosmetic slot wheel. Each victory gives you the opportunity to wear your trophies and make your friends jealous. 
Lobbies are meant to be fun, open spaces for players to parkour around, equip new cosmetics and emotes, and get ready for the next race while the host is emoting off to the side.
