The game have simple mechanics and the explanation isn't too hard to figure it out. To take control both keyboards and mouse at the same time can be challenging, but it seems fun. The concept is great, but I would prefer the design to be better. Overall, the game is good and I'm hoping for future developments.
Also, the description, "game where a friendly ghost has to help player 1 get through a scary temple", I don't think it is a scary temple. More like, deadly and dangerous.
