【フローティングフロア】ぐらぐらの床を移動して狙った術を獲得するバランスゲーム / TGG ボードゲーム

About Floating Floors, from BoardGameGeek:

Floating Floors is a tactical balancing duel in which you, a ninja, become the architect of your own domain, creating a labyrinth of floating floorboards for your rival to cross. In more detail, you create a stable path to your target by balancing a labyrinth of floorboards that will also be used by your rival. The trick is in strategically using your jutsu tokens to keep your new ninja camouflaged with the surroundings, while sabotaging the rival ninja's path. The first ninja to claim all four bansen seals, concealed by your rival during set-up, wins.
