Romio, I and a handful of other people on the discord server played this map and I gotta say it's solid. I had a lot of fun with it. One thing that needs a serious overhaul is the textures. By that I don't mean you need to change everything, just one simple (but important) issue. The huge outer walls have the same small tiling texture that the landscape structures have. That's just not visually pleasing. Choosing a texture that a) is darker than the foreground textures and b) is wayyy larger and isn't obviously tiling would help dramatically.
As far as gameplay goes, the slopes definitely provide a lot of action in a lot of areas of this level. However, there are still some issues. There's this long bottomless pit room with a few rows of springs in it that you get launched into via red horizontal springs. A lottttt of people in the discord server had problems with this. If you're playing as any character slower than sonic, and somehow get out of your spinning animation before getting launched into the pit, you won't have a chance of traversing it. In contrast, some people had trouble slamming into the first wall obstacle of that pit, which happens if you don't strafe. I'm all for encouraging people to strafe, but maybe just make this pit a bit more forgiving? It's near the start of the level, after all.
Regardless of this, I had a lot of fun playing it. It's a good length, it looks like an actual canyon, and it has a lot of fun ideas. Not to mention the two secret rooms (one of which I actually found without looking in zone builder lmao). If you could just make these small but significant changes, this level would be even better as a result.
