- Creepy Cute: For an alien that can teleport inside you and cause you to explode, Zero is pretty adorable.
- That One Level: The final level of the game, the submarine. For the entirety of the level's duration (up to and including the last boss), the level will slowly rock back and forth, causing both Zero and every barrel to slide left or right. The problem is that the movement isn't exact, and often has a slight up/down movement as well, though not always. It turns a level that requires a lot of precision platforming and quick reflexes into a bit of a Luck-Based Mission.
YMMV / Warp
