We have to admit that when we first fired up the trailer for Core, we weren't convinced. For whatever reason, simple art style and warpy music didn't really grab us.
Keep watching however, and a rather intriguing puzzler starts to emerge, one which involves connecting and layering wires so that orbs can transfer energy to a corresponding square. Have a look for yourselves.
Each puzzle seemingly has a few options, but the goal is to have the orb reach the square as quickly as possible. The game is free to download, so if it looks like you'd enjoy making a few new connections, you might as well give it a try.
