Ya level 9 its literally perfectly timed so you can't make a mistake and you have to go through the maze and then back. Certainly designed to be a real challenge. It's getting me to the point where I'm working on angled movement based on pressing down and left or right to save time around corners.
Considering the level of graphic emulation, all of the sprites are distinct enough for the player to interpret what everything is. Poor guy though. Looks like he lost his head running through all those bombs. Great work!
