What's Spirits? Spirits is, basically, the Lemmings. It's the same concept. You must guide your spirits to the end of the level.
You can ask your spirits to sacrifice themselves to open the way (Growing a tree, making wind, digging the ground...), or just let them walk around to see where they can go. It's a pretty simple concept, but it's still a nice one.
The music is just fantastic. Some sound in the menu are earrapes (buttons), but except those ones, the sound is beautiful during the whole game. Graphics are shiny n' cute, the whole game is played in a Orange-Black-White tone, it's nice and relaxing.
You can buy it via Steam for 8.99€, or via the Humble Bundle store (link : https://www.humblebundle.com/store/p/spirits_storefront
) or 7.49€.
Conclusion : It's a pretty little game with nice level design, nice graphics, and a nice price.
