Second Sunrise

Rebirth a solar garden once, then store thirty-two energy before thirty-six ticks. Four marked plots hold east- or west-facing panels. Build costs 2 energy; choose East or West and tap an empty plot. In Fuse mode, neighboring equal-rank panels with the same facing combine at the second plot, reducing night maintenance. Dawn pays twice each east rank, noon pays every rank, dusk pays twice each west rank, and night costs 1 per panel. Each build, fusion, battery upgrade or Wait resolves the displayed sun phase. Battery capacity starts at 8; upgrading costs half the current capacity and doubles it, up to 32. Rebirth requires 16 energy and a selected rank-2 panel: it consumes the energy, clears every other panel, doubles the survivor, retains battery capacity and restarts at dawn. Selection and mode changes are free. Keyboard: Tab and Enter/Space operate buttons; R restarts.
