Around the Boost

Alright, without a walkthrough video available I think I was able to check the intended solution via the comments ;-)
1st maneuver/area #1 (ninja shot) : it worked for me on the first try, not my favourite kind of move but I accept it, though I expected a different way of connecting the rooms.
2nd maneuver(s)/area #2: finally finding a way to create the null portal was a great aha-moment! Then being able to use more of the stuff around that area including both floor portals for a cube juggle felt very satisfying too. Once these obstacles were taken, the rest of the puzzles were easy to find. Thumbs up!
P.S. The elevator might be a bit misleading as it is never used to get up (which is of course impossible since you can't sacrifice the cube from down below), so a different kind of blocking element might be better imo.

This is a very cool card.

Mostly same experience as everyone else. Thought first part was cool but due to poor controls had to play a little with host_timescale for one move. Second part had some clever cube and portal preservation moves. I'm usually not a fan of the old aperture styles but I think this one was constructed very well.

Originally noclipped past the first puzzle in frustration when I looked in the comments and saw a ninja move was required. I don't see such things when I'm solving--grew up with with a much different style of video game from all the younger guys here. I was disappointed, but wanted to see the second half...which ended up being really cool. As crhoaviet6 said I really liked the
fizzler portal reset thing - would never have guessed if I hadn't gone through the series that had that as a major theme 6 months ago or so. Don't know how long it would have taken me to set up the cube juggle had I not seen mention in the comments when I was looking for help with the first half. Done it before, but sure comments helped. . The second part made me go back and find the move in the first half. Lots of F6/F7 but finally got it. Second half made me want to get first half--glad I ended up doing it all.

Beautiful Hammer work as always.

I had no issues with the first puzzle. The shot is quite doable, especially if you're not going too fast. The second puzzle was my favorite, especially the first move. At first, the ceiling fizzler just seems to be an obstacle - but you can actually use it to your advantage! Brilliant.

Yeah it's a crap map. :(

I'm a better-than-average player, but I can't solve this one. The one walkthrough video below shows the player just miracle-leaping to the platform where the1st part's exit door is. Don't know how that's possible. So I'm out.

The test chamber is good in appearance and hard. But I don't like her very much.

Not a huge fan of the first puzzle, but the second is beautiful :D

Design is pretty good! I haven't seen a lot of maps with clever using of orange gel, so that makes this map is one of the best puzzles. Great job!
