How to play

1. Swipe (touch) or use the ← → arrow keys (or A / D) to steer. Hold ↑ Up (or W) to surge forward faster — let go to drop back to your normal speed.
2. Fly through the token that turns your ship's number into the gate's target, then line up with the opening — exact and aligned clears the gate.
3. You carry 5 shields. Each miss costs one — lose all five and the run ends. Every 10 gates cleared restores one shield.
4. Pick a mode: Progressive moves you up a grade every 10 gates (speed resets each new grade); Single Level keeps your grade and just speeds up every 10 gates.
5. The numbers adapt to you: miss a few in a row and the operands shrink; string together correct answers and they grow.
6. Need to stop early? Tap ✕ Quit (lower-right) to return to the menu.
