I think that the lack of good instructions makes it look more complicated than it really is. The game itself can be compared to chess (which is easy to learn but hard to master). In chess pieces have two "parts": piece type (bishop, rook, etc) and color (black or white). In Symbiosis flowers can be compared to the type of piece in chess, they determine the way they "attack" but instead of attacking they affect the tiles with their pollen. The color of the pieces can be compared to stems, two pieces won't be able to kill each other if they share the same color; same rule for Symbiosis. Finally, leaves just give extra points to the player if two adjacent plants share the same leaves; this adds an optimization aspect to the game. Leaves can totally be ignored if the player just wants to win the level. The main reason I decided to do modular plants was the possible amount of combinations, with 3 flowers, 3 stems and 3 leaves I get 27 different plants. Thanks for the valuable feedback btw!
