Last week, we made the piece flipping more lenient for players who hit the two buttons a few frames apart. But a very naughty player noticed you could abuse this in a very silly way to warp pieces across the playfield. Naughty, naughty! We've given the piece flipping behavior one more tweak to prevent further naughtiness.
There's also a handful more minor bugfixes and stability improvements here and there, including one more attempt to patch the elusive bug which is causing the game to suddenly exit after a puzzle. Let me know if you see any other weirdness, I'll try to get to the bottom of it!
