Really nice map! Looking at your profile it seems like your first?? Couldn't tell it from in game honestly. Quite fun beginner map, I can see this map being a hit.
I had myself & 2 others test it, runs pretty smooth at 102.4t, we haven't experienced any ramp or textures glitches so far. I've attached a screenshot of each stage :)
Only overall improvement I could suggest is textures. Don't get me wrong a 7MB download is great but the textures are a bit bland (I'm sure you're aware). Having the ramps so close to other colors on the same palette isn't optimal in my personal opinion.
*I've noticed a tiny texture issue on stage 4 at the bottom of the first ramp on the right. It looks like a grey concrete texture from the ramp on the inside is barely showing through, I've attached 2 pictures to help identify it.
