- It's Easy, So It Sucks!: E4's Endless mode is not taken seriously by most players, due to the fact that it's easy enough to survive for hours thanks to the abundance of time extension items. You practically have to try in order to run out of time.
- Sequel Difficulty Drop: Survival is completely trivialized in Extreme compared to its predecessors. In Unlimited mode, if you are fairly on top with picking up Time Extend powerups, it is possible to play for hours without needing superplay-level skill.
YMMV / Every Extend
