The solution is amazing! You really have to think outside the box and it felt really satisfying completing this.

Do you wanna know how long it took me to complete this? 2 hours 15 minutes! SERIOUSLY, Valve needs to hire you to help make Portal 3, because this is the sort of difficulty needed near the end of the game! Love it!

Chamber 5 cost me more than an hour... But finally I made it!Firstly I attempted to use normal ways but all failed.You must break the routine to solve it.This puzzle is very imaginative and a bit challenging...

实验室5花了我一个多小时才搞定... 一开始我先试了各种常规的方式但是都不行。想过关要学会打破思维定式。我只能说作者很有想象力,非常有挑战性的图...

You are an evil mastermind when it comes to making Portal 2 custom levels.

The ending of the last puzzle is so clever! Nice job.

I like these, but at the same time they have a really weird vibe to them. I feel like a couple of them I solved, but I didn't do it the right way. I know there isn't really a right way, but there is an intended solution, and with all tricks I did it just felt like I was breaking it. I like that.
