Add minigame Star Collector (Level 2)

[MonikaSvata]

Adding a new minigame to the AstroBalance project.

Level Description

Therapeutic Goal

Tracking moving targets with opposite head motion (yaw only).

Core Mechanics

Ship moves in the opposite direction of head, collect falling stars.
Success: Collect 100 stars or play until time limit.

Long Description

The spaceship moves horizontally across the screen (left-right) in response to the player’s head motion but inverted — if the child moves their head left, the ship moves right, and vice versa. There is a visual fixation dot on the
astronaut’s helmet. Stars fall from the top of the screen sinusoidally at increasingly faster speed. The speed of the ship is automatically adjusted to match head speed and accuracy. The game ends once the child has collected 100 coins (rolling total in the edge of the screen) – this should take 1 minute initially, progressing up to 3 minutes (based on star density).

Adaptive Difficulty

If frustration is detected with errors, it should slow star speed. If there is a high success rate, then speed increases slightly and gradually increase duration of set (up to 3 minutes).

Rewards

At the end there is star dust/confetti and a well-done me
