Instant travel speed for the lift

lift.y = 0; lift.speed = 30;

Allow up to 100 workers on the first floor

shafts[0].max_workers = 100;

Allow up to 10 workers per shaft

for (let i = 1; i < max_shafts; i++) shafts[i].max_workers = 10;

Despawn all workers

shafts.forEach((shaft) => { shaft.workers = []; });

Accelerate the game x10 (this might be more power hungry)

Array.from(Array(10)).forEach(() => animate());

Get paid $10 for hiring a worker (you pay $5 and receive $10)

shafts.forEach((shaft) => shaft.workers.push = function () { score += 10; return Array.prototype.push.apply(this, arguments); });

Cool game OP :)
