Tap or press Space to drop. Every 5 blocks the tax shaves your block - perfect drops win the width back.
The collector's cut starts at 10px and grows by 3px for every 10 blocks of height. Perfect drops hand width back, but the cut keeps climbing, so sooner or later it outpaces even flawless stacking. The question is not whether the tower falls - it is how high you get it first.
Land two perfect drops in a row and your block grows a little; three grows it more, then the streak restarts. Precision is the only thing that undoes the narrowing.
Stack Tax keeps the classic stacking goal - get as high as you can - and puts something in the way of it.
You are taxed twice, and both cuts take the same thing: width.
The tax you earn. Miss the alignment and the overhang is sliced off - every sloppy drop makes the next block permanently smaller. That is a tax on your own hands, and it is charged on every single move.
The tax you are charged. Every fifth block arrives narrower whatever you did, marked TAXED so you know it was not you. Even flawless play loses ground to it.
Precision is the only rebate: two perfect drops in a row give some width back, three give more. How high you get is the whole score.

Height, and only height. There is nothing to bank and no reason to stop early, so the whole question is how far up you get.
That is the tax. Every fifth block the collector shaves the next one whatever you did, and the block arrives marked TAXED in red so you can tell it apart from your own mistake.
Yes. It starts at 10 pixels and grows by 3 more for every 10 blocks of height, which is why no tower stands forever.
Perfect drops, and only in a row. Two in a row hand back 20 pixels, three hand back 30 and then the streak restarts. The side panel shows how far into a streak you are.
Yes, twice over. The window starts at 10 pixels wide and tightens to 3 by height 35, and the block is sliding faster the whole time.
