Tetrollapse

You control the familiar falling tetromino shapes, rotating them with the spacebar and moving them sideways with the arrow keys. The main objective is to clear lines, but the twist is right there in the name. Instead of building from an empty well, you start with a dense cluster of pre-placed blocks at the bottom that you must clear away first. This creates a puzzle-like layer on top of the usual race against time. The pacing feels deliberate at the start as you carve out space, but it quickly accelerates as the new blocks fall faster. It feels like solving a structural problem while under increasing pressure.
