Addition

For the second puzzle, if you're stuck you might want to read this hint:
You can paint the cube with propulsion (orange) gel. I think many people didn't even know this was coded in the game or never used this.

2nd time round solving and this still took me FAR too long! :-)
I was forever trying to work out how to get the Orange Gel on the ramp to get the cube on the button, when I suddenly realised there was a grating at the bottom which would prevent the cube from sliding that far Eureka!
Great map

This one was definitely challenging until you have that ‘Eureka!’ moment. Another excellent map—thank you for creating it.

Blindrun
First one wasn’t too bad, but dunno why I didn’t realize I didn’t need the runway at the last part - nor was it possible to use it sooner. Only solved the second chamber when I looked at the comments and received a little accidental inspiration: you could argue that I got spoiled a little, but I literally only saw the words ”cube” and “cover” . The second I did so it clicked immediately what needed to be done. The inspiration could have come from literally anywhere else, and likely would have had I not figured it out entirely on my own in due time, so I consider it merely time saved personally.

While it was very stupid of me to not think of the mechanic earlier, as it’s used in a chamber in Portal Stories: Mel , it also would have been nice if it were hinted at a little more explicitly somehow, or perhaps have a similar mechanic introduced in a prior chamber. I suppose you could argue that the shape of the panels give away that something (the cube) is supposed to be “dumped down” below, as opposed to a portal linkage allowing the player to manually place the cube on the fizzler button , but I couldn’t help but feel I needed to do it the other way. I guess you tried to hint at the proper solution with the arrows, but I kept assuming the floor was what needed painting, not the cube.

I can’t remember whether I caught it on tape or not, but I did experiment with cheesing it via placing a portal in the ramp room, placing the cube at the edge of the button, and throwing it into the portal , so I probably could have made it through the door anyhow.

In any case, for the multiple cases of ingenuity present throughout this chamber, this is getting the highest score yet out of any of your puzzles (besides Polarity), and also the highest difficulty rating (also besides Polarity). And, of course, a favorite.

Difficulty: 7.5/10
Enjoyed: 8.5/10

I can't find walkthrough for the version i've got :-(

how you make these maps work out is amazing.

第二关提示： 1.箱子要涂上加速凝胶，2.有加速凝胶设备的房间走到底，利用一个狭窄的视角开启加速凝胶设备的房间与外部房间的传送门，3.控制翻板的房间可以不使用箱子开启翻板按钮（与涂箱子的方法类似） ， 脑洞比较大，根据留言中汇总的3个主要提示，还是完成了测试
