An awesome proof of concept. Worth updating more. A track that doesn't exist because without video game building tools it would be nearly impossible. Akin to driving on a mix of dam road and canyon with nearly zero thought given to safety equipment (such as guard rails), the track is extremely challenging and rather unforgiving. Despite it's rainbow road appearance in layout, driving the track feels good. The asphalt is smooth, and only in a few instances will you find bugs. You'll want to stay on because falling off in certain places will have you fall straight through the world. In other places, sliding flat to the guardrail might get you stuck.
While it could use some update for night driving (either brighter Tron-like emmissive markers or street-lamps or something similar) it will challenge you even in daylight, with long inclines both up and down, transitions through tunnels on the downhill in arcs and even a jump. It's worth the download just for the novelty. Hone your skills, as it's very easy to overcook a few corners and slide off the edge. On the plus, in a multiplayer setting, the track lends itself to self-clearing. It can make for some hilarious memories, regardless, especially drifting/touge with friends. Comes with bonus sections of track that change up the layout a little bit on the fly.
Worth checking out. Ticks most if not all the right boxes in a package that is truly fun and challenging while redefining the term nerve-wracking.
Rating is 4/5, only on grounds of the occasional bug, and it's oh so dark at night. So, so dark. Needs better track lighting. Verdict: Recommended 100%.
