Huh.

Seems like it would improve replayability if they were randomized. Otherwise, once you figure out which are the magic plants and how to get there, new games are just a race.

Anyhow, thanks for your replies so far. Two more questions: When I water the plants, the water gauge goes up and is blue up until somewhere between the letters "A" and "W", after which it becomes red.

Am I overwatering the plants when the gauge turns red? If so, what are the disadvantages of overwatering?
