The first five aircraft — Iron Bird, Falcon, Rayce, Vanguard and Hornet — are now unlocked from the start. Each one plays very differently (laser, spread, homing, charge-focused, drone escort), and our data showed most players never got to try a second aircraft before the old unlock conditions kicked in. The five late-game aircraft (Bastion, Spectre, Apollo, Prism, Titan) remain unlock rewards. Existing profiles get the new aircraft with a NEW badge.
The "aircraft unlocked" achievement now requires 7 aircraft instead of 5, so it isn't granted automatically.
Demo: the free demo now includes the same five aircraft (was three), and its ending screen opens the Steam store overlay directly.

After a few runs, the results screen will ask once whether you'd like to leave a Steam review (press R). No rewards attached — it's just the most useful thing a player can do for a one-person studio.
Thanks for playing and for the reports.
