Mana Mosaic

Create a 64-value rune and place it on the central mosaic altar within fourteen rituals. In Merge mode, tap two adjacent equal runes; the second receives double value and you gain 1 mana. Empty cells cannot be walked into. Blink costs 2 mana: select a rune, then any empty non-wall cell to teleport it. Double costs 3 mana and doubles the tapped rune. Meditate restores 1 mana but spends a ritual. Each successful merge, spell or meditation uses one ritual; mode changes and selections are free. The two separated groups contain exactly 32 value, so at least one Double is essential. Save enough mana to bring the finished rune to the center, not merely create it in a corner. Keyboard: Tab and Enter/Space operate buttons; R restarts.
