🎮 Cascade Control Flick juggling balls to the correct siteswap height, catch clean throws, and clear seven escalating patterns. 🎮 The Day the Sun Cleared Its Throat A minesweeper-style deduction puzzle on an 8x8 VLF spectrogram across 5 escalating levels: read the warning numbers to find and flag hidden solar flares without probing a live one, while a GOES X-ray ticker maps each ionospheric disturbance.
