This is a devious little puzzle game. You are trapped and must find your way home. But to do so, you must plant and harvest seeds to grow different types of paths. And if that isn't tricky enough, you must also collect keys to open doors when the world inverts, shifting from light and color to dark and filled with stars.
The clues to what you need to do are subtle. So subtle that some people might not get them at first. They appear as poems written on the walls of the level. But even without the poems, the longer you play the more you figure out.
There are two types of seeds that are very important. Pink seeds grow pink paths and when you harvest the pink blocks, you gain more seeds to grow more paths. However, the pink seeds grow very slowly. Green grass seeds sprout areas that have hearts in them. When the world inverts those hearts will turn into stars, which you can harvest to use for seeds back in the main world. Each type of seed creates a different type of path with different properties.
Getting to the first two levels is easy. The third level requires collecting three keys and going through a door locked by three keys - which aren't all that easy to find.
The music is interesting, as each seed grows with a different tune, making for changing sounds throughout the game.
If you like devious spacial-awareness puzzles, I recommend spending time to try to figure this one out.
