TRACKMANIA 64

What would Trackmania looked like if we played on an old device of the Nintendo64 era, so a few years before the first Trackmania game ?
I tried to make a track with this constraint.

Obviously it has a huge impact scenery wise, it's 99% custom blocks (+water blocks hidden underneath custom items). However, to respect a low poly style, I didn't allowed myself to use any smooth slope for the way either. So any slope would have an hard edge at some point. It forced me to think about different ways to transition onto slopes, using jumps and water bounces.
