[Portal 2] Speedrun of laser platform in 28.48s

Speedrun of the Portal 2 challenge mode chamber "laser platform" in 28.48s. Rank ~35 on the steam leader boards (steam leaderboard rankings are approximate as they do include some illegitimate times). Leaderboards can be found at http://steamcommunity.com/stats/Porta... Any feedback, tips, advice etc. in regards to either the video or the game play itself is greatly appreciated (and feel free to be harsh, I can take it). If you have any questions feel free to ask in the comments or pm me and I will try to respond asap.
