The game is based on exploration basically, with the aim to find many crystals that provide energy to plants, so they can grow. Grow on and you might eventually make it back to your MOM (mothership). The art style is interesting and fun. The exploration, which next to climbing mountains, isles in the sky and searching thorugh caves also includes researching plant species and animals, was enough to keep me going for that 100%. The power-ups your cute little robot gets are nice too. The game is not so long, but just long enough to let you play with all the mechanichs and explore the areas without getting bored. Very well balanced. All in all, a fun game for a great price.
