Skul: The Hero Slayer
Developer: SouthPAW Games
As most roguelike games, Skul: The Hero Slayer (Skul) was designed to be HARD. The objective is simple, beat all game levels without dying. Yes, you can beat the game in your first try, but you won't. YOU WILL DIE and start again from the beginning, not just once, but several times. RNG has a HUGE influence on the game. There is a big difference between items and skulls performance, so to beat the game you will need luck and skills. To have fun playing Skul, you need to accept the gameplay challenge and don't consider a reason for frustrations. Last but not least, controllers plays much better than keyboards.
