Issues, galore.
1) Player movement gets stuck on inanimate objects. For example, if you sprint down a stairway, you'll most likely get stuck on its railing when you turn the corner.
2) Player movement gets stuck when you start over repeatedly and have your fingers on the buttons, ready to go.
3) You're given an impossible task of beating a nine-minute clock during one of the missions, which requires you to boringly die way too many times. I sprinted through it, killing everyone along the way, but the slow opening door messes it all up. Game is ruined because of this.
