This is probably the last version by me.
Features:
- Linux native
- time, 3BV/s and IOE high scores, including percentiles and non-flagging versions
- scores kept indefinitely for all played games
- recording and playing replays
- CSV export
- timing in milliseconds
- responsive on slow hardware
- adjustable square size
- to reveal squares around a numbered square with flagged adjacent mines you can click the square with any button
- no "?" marks
- pause
It's decisions like the lack of client side decorations, a sys tray, and mouse cursor protocol that makes me wonder what direction they're going for
