Koi Pond
Your fish follows your finger or cursor and darts when you hold. Eat to grow, dodge the predators, and open the way out of each area by solving its clue or winning its minigame — there are twenty, from lily hopping to shoal herding. After the tenth water area the koi becomes a lizard and the game moves onto land for ten more. Every area is generated and every creature is drawn in code, in soft flat colour seen from above.
