Boss fights, rebuilt: every boss now fights in three phases. Between phases it shields up in blue and sheds plates of armour, then comes back with a new pattern. Its health bar always drains, and no phase drags on. Bosses go down in a longer death sequence: the hull chars, heats white, goes quiet, then ends in one blast with shockwave rings. Enemy fire you can read: shots have a white-hot core, a flame ring and a dark rim so they show up on every stage. Each kind has its own shape: a red orb and a magenta capsule. High contrast mode draws them in pure white and black. Stars you can catch: loot arcs up and rains down trailing gold. Catch it high for full value, and fly clean for double stars until your first hit. Every boss ends in a payday fountain of stars. Your first upgrade is in reach after your first clear, and when one is ready the results screen takes you straight to it in the hangar. Endless and the Daily Challenge now bank 30% of their stars, so the campaign is the place to earn. Fairer hits: only the drawn plane counts. Its wings can be hit, but clear air around it can't. Near misses spark and score once the shot has truly gone by. Calmer when you need it: with Reduce Motion or Dim Flashing Lights on, every flash and blink calms down while warnings stay readable. The score and hull readouts step aside when shots pass under them, and power-ups carry glyphs for Differentiate Without Colour. Smoother victories: the star shower after a big boss no longer slows the game down. Mega Bombs now take a tenth of a boss's health and can't skip a phase.

Game Center: three leaderboards and nine achievements, with progress towards the tier, endless and medal achievements shown as you go. New ways to play: Endless mode on the art of your furthest level, and a Daily Challenge with a fixed jet, one attempt a day, on a shared leaderboard. Medals now pay: each medal earns stars the first time you win it on a level, the results screen tallies them up, and the level list shows what a return visit can still earn. Replays of beaten levels bank a share of their stars, and the hangar says exactly what the next upgrade buys. Feel: every hit, boss and bomb has its beat. Enemy fire is easier to read, near misses score, ground units leave wrecks, and the killing blow on a boss lands in slow motion. Music ducks under the pause menu and the boss alarm, and Resume counts you back in. Accessibility: Dynamic Type across the menus, a Reduce Motion path for every effect, a high-contrast option for enemy shots, a striped hull bar for Differentiate Without Colour, VoiceOver labels and announcements, the bomb button on either side, and a Replay Tutorial button. Balance: the campaign was retuned with an automated playtest so every level is finishable on a fair jet, with the big bosses at 10, 20, 30, 40 and 50 the peaks.
