A giveaway and I just installed it and played it, because it did look fun. However, it is just a clicker game. So if you don't want to buy a new mouse because of wearing out the left mouse button.. just activate a macro handling the clicking. Good thing is that the game doesn't take much time to beat at least. One big downside is that it is unreasonable resource heavy, which can be fixed by capping the FPS via Nvidia Control Panel.
