A friend in the corner Every world's kitty now keeps you company while you play, and cheers when you solve a level. Fixed In Bubble Reef, the arrow warning about the current no longer jumps to the corner of the board when the push is close. Also Tidier spacing on the worlds, map and level screens.

Worlds A new map above the levels: pick your world before you pick your level. Four are visible already, with more on the way. Bubble Reef An optional pack, twelve new levels underwater with a current that pushes the board. One-time purchase, restorable on any device. The original twelve levels stay free. Also A quick way back to the home screen from the level map.

Par scoring Every level now has a par, counts your moves as you play, and keeps a best score next to your best time. Undo is free: it never costs you a move. Pause A pause button, and the clock now stops on its own when you leave the app. The cat naps over the board, so a pause isn't free thinking time. Purrville Map 1 has a name of its own, and a background to match. Also A fourth tutorial step that explains par, and all twelve levels recalibrated so each one is really harder than the last.
