0.9.2
The falling piece can cast a shadow where it will land — the ghost piece. Off by default; turn it on from the settings screen's second page. It changes nothing about how a round plays.
Eight new colour palettes, for thirty-two in all: the eight schemes Windows 3.1 shipped in its Control Panel, named as it named them — Hot Dog Stand included.
Your saves carry forward. Settings and high scores from 0.9.0 and 0.9.1 are read and kept.
Downloads are now archives — the Linux and Windows builds ship as zips holding a single folder, and the Linux executables arrive ready to run. macOS remains a signed, notarized disk image.
As before: the game asks for your Tetris ROM on first launch and reads its graphics and sound from it.
