Total time (including deaths) = 28 minutes 18 seconds

Summary: Simple designed levels but have some great ideas put into them.
Portal Wall Jumping in the first few levels was very fun. Portal Falling on the other hand was quite frustrating since you have to time your jumps carefully and more than often you tend to mess up.
I really liked "Portals 07". Fast paced action at it's finest.
The Portal mace afterwards was very unique and well thought out. Personly would've put in two portal (instant kill) traps.
Loved the idea of inverting the stage in "Portals 5" whenever you'd go through a portal. The last jump was very tricky.
"Portals 9" is probably one of the most fun levels I've played. Being chased by a unstoppable size increasing portal that launches you into a death trap as soon as you get caught is simply awesome!
