Night Veil is an interesting puzzle/arcade game that feels delightfully retro, not unlike something you might see in a pub arcade machine.
Gameplay consists of moving around on a grid of rings and placing chains between them. Moving between rings once connects them with a line, once more creates a chain. But go over the chain, and the rings will once again be disconnected. These rings will sometimes hatch ghosts, though, which will follow and attempt to kill you. The only way to stop these ghosts is by fencing in an area with chain and trapping them inside, which will destroy them. The object of the game is to fence in small numbered blocks with your chains.
Night Veil is an interesting arcadey puzzler that feels a bit like Qix and a bit like Pacman, but will no doubt have you scratching your head frantically as you try to figure out a path between the rings that will destroy your pursuers.
