Fixed the arrow overlapping the frame on the language and graphics quality menus in Settings. The Remove Ads guide now notes that Undo is also granted without ads.

A short guide now appears the first time a new diagonal line shows up on a larger board. Short diagonals that cut across a corner are introduced the same way.

Improved button labels and visibility on the level clear screen. The remaining undo count is now shown more clearly.

The start screen now lets you know when a new version is available.

New background music.

Updated graphics and sound. Fixed a few bugs.

The stages after the campaign have been rebuilt. They pick up at the campaign's final difficulty, and boards grow from 6 by 6 up to 9 by 9. Lines now run at a wider range of angles. After you clear every stage, Endless mode continues at the same difficulty. The gargoyle's eyes and pedestal runes glow in the element's color, and each shot now has recoil and a puff of dust. Sparks and spray scatter more naturally, and the air beam looks more like wind. The company logo on the launch screen is new. Some in-game text has been reworded. Because the stages were rebuilt, star records for the old stages are reset. Campaign records and progress are kept.

• A new look for Earth — rocks are replaced by a sunlit ochre mound of soil that fills the cell more fully, with scattered crumbs and pebbles for an earthy feel. • Clearer aim cancel — drag back to where you started, or well off the board, to cancel. The guide turns grey before you let go, and dragging over the element dial now cancels reliably.

• Smoother line drawing — the line you meant is picked even with a shaky finger, and overshooting past the end of a row no longer cancels the shot. To cancel, pull sideways off the board. • Clearer aim guide — easier to see over bright cells, with an arrowhead showing where the beam goes.

• Much smaller download — the app is now under 100 MB (down from about 300 MB), so updates install faster.

• Better tablet layout — the board now scales up on iPad and other tall screens. • Tightened title and number alignment across the UI.

• Resume anywhere — your current puzzle is kept when you change the language or leave the app, and the title screen picks it right back up. • Star goals on the HUD — see your shot count and the 3-star target at a glance. • Better hints — hints stay on screen, and showing the same hint again on the same board is free. • Clear help costs — Continue and extra Undo now tell you how they affect your stars before you use them. • Level select — the current world's progress and the next level are highlighted. On first launch, Daily Challenge opens after the tutorial. • Board readability — stack depth badges, plus clearer empty and Earth cells. • Fixed Daily Challenge results overwriting campaign level 1-1. Existing progress carries over automatically.

Adjusted how often interstitial ads appear between levels.
