Black Knight Sword
Really nice looking Suda51 game
The game on its own is hard, i finished it and it was hard but fun
The challenge mode is brutal, but i've done it with lots of screaming and hair tearing
Arcade Mode is nigh on impossible, i literally quit gaming for a while because of it
She Wants Me Dead
2D black and white side scrolling platformer, 1 hit kill, and all the traps are played to the beat of the games main theme song.
Again, plenty of fun the first time round when you can take your time and have quite a few goes at it, but then you start looking at the trophies and oh man does it get depressing. Finishing the whole game on a time limit, and finishing the whole thing from start to finish without losing a single life.
