Build Blocks Wii - simple 3D sandbox game with blocks for Wii. There's no objectives, you can just freely build stuff with blocks on board. Ported from my Nokia S60/Asha version which is available here: Full version and here: Trial version.
There's no gui yet, and you can only place/remove blocks on 8x8x8 board. Up to 4 players on one screen are supported. Standard Wii Remote is required for controlling stuff. 16:9 and 4:3 TVs are supported. Should also work with Wii U on virtual Wii mode, but this is not confirmed yet.
Anyway it's first test build so don't expect too much from it.
