So I got the rc1 version, and the map is really smooth and fun. One of my biggest complaints is that some jumps with surf to them have an ending platform that are unsatisfyingly close. LET FLY, MAN! You also seem to have removed numbers on the jumps and bonus doors, so I can't list which ones without having to manually go to the bonus, count the doors, then make sure I guessed right... But spread out some of the long ones. I need room to spread my wings, you know? For example, on the bonus, could you raise the ceiling a bit and make the last gap maybe 2-2.5x longer?
Also, on one of them with a triangle-ish platform (V with a _ on top) used to skip off of, you can surf and rocket off the V parts. Not really a problem and made it a bit interesting, just thought I'd give you a heads up in case you didn't like it.
I loved the end area. I can't even guess how long I was in there just going around in a circle. lol It was a bit meh in the first half, but I loved the second half. Very smooth <3
(One last piece of advice, can you please size down some of the textures? Mostly the gravel one. It makes me feel awkwardly small in these larger areas and is being stretched, as you can see the pixelation in it)
