It looks nice. :) But i don't know to bhop. :(

Had a playthrough of it.

It's a nice remake of the original and looks much better. I like the skybox. Overall the map is still quite easy but enjoyable nonetheless. It also felt a bit short to me but that may be because of its easiness. I liked the climb too, and that you could bypass those lasers later on if you did it (although because your gravity isn't reset on respawn I can bypass the climb and still make it through the hole). The addition of the moving things on the walls was nice but still easy to get around. Perhaps have one you have to jump over/through, or have multiple ones on each wall. I liked that you made the sets of 3 blocks random too (before the bhop that's before the lasers). The guns at the end were also nice to fly around with and the smoky boots from the longjump were pretty awesome (consider putting a roof above the longjumps up to 250-260 so people can't bhop it 'til then).

Speaking of the guns at the end, if you kill yourself with low gravity you keep it when you respawn. You should consider having a small spawn room that just resets your gravity then teleports you to the start or something, perhaps have name-filtered trigger_gravity triggers at spawn then parent a trigger to the end weapons that set the activator's name On\StartTouch and then set it to something allowed by the spawn trigger On\EndTouch.

Oh and you can completely skip the triangle hops after the surf if you jump to the right, surf along the glass and then jump onto the last triangle. Speaking of glass, did you build your cubemaps (if you have any)? All of my reflections are pink and black. If you fall from the top of the climb block you can fall out of the map without having a way to get out without killing yourself, maybe add a teleport down there. The teleport around the surf part doesn't go around the base of the start tower that you jump off of either, but this is minor.

I liked the secrets, by the way, although I haven't figured out how to properly get into some of them. I figured out how to get behind the triangle hops area then get the sword (which doesn't seem to parent properly, try moving the origin to the handle (if you can't, just make an invisible, non-solid block the same size as the sword and flip it around where you want the origin to be and make it all one entity, eg. [block]o[sword] where o is the origin). The sword's quite annoying to have blocking most of your view, by the way. I found the "fans" at the surf part and the skate ramp but haven't figured out how to properly get to them yet and I'm not bothered to decompile it etc. I say "fans" because the way you've done them annoys me. Fan blades need to be at an angle, else all they do is blow air out to the sides. Make the blades thinner and rotate them, that's all, perhaps even give them a curve.

Good job, anyway.

Almost forgot, why are you using what looks like dx7 water? People can force it if they need higher fps, can't they?
