The playable prototype of Apparatus game for Windows 64-bit.
After downloading run installator.
If you set fullscreen mode and see the black screen with sound, turn off the fullscreen mode by pressing Alt + Enter. If you want to use fullscreen mode in this case, you have to disable fullscreen optimization by clicking right mouse button and check it like on this image: Imgur.com
For now I can prepare demo only on Windows, but in future there will be Linux and Mac versions.
Enjoy!
