Kostyantyn Salanda’s organic physics-puzzler Biosis is currently free on the App Store.
Dragging a glowing blob through Biosis's puzzles quickly becomes a greater challenge than you would expect. Your tiny globular ward is pretty useless and relies on you to activate a variety of creatures and plants in each stage to push and pull it towards its goal.
A slow starting pace gives you plenty of time to come to grips with the game’s world manipulation mechanics. Give it a little time, though, and you will find yourself firing your blob like a cannonball across the map in order to grapple it with a vine before swinging it safely into an exit.
Exploring the lush habitats of Biosis was an experience we really enjoyed, with its blend of environmental exploration and twitch reactions managing to create a nice variation on a familiar puzzle concept.
Biosis is currently free on the App Store, making it wellworth delving into if you haven’t already.
