In addition to the whole teleporter thing...

I don't know how it's always going to be a maze if you include multiple routes. I know many amazing tracks with multiple routes, and to be honest, most of the best tracks have multiple routes.

These 2 are some of my all time favorite tracks, and they have multiple routes, and I think that that is a pro and not a con, and that it does suit the 'frhd style'. Right now you don't see too many tracks with multiple routes but that's because there aren't too many great authors on FRHD yet that are willing to put the time and effort into their tracks to make it have different routes, so obviously all the tracks you see on trending are mostly straightforward jump based tracks.

So yeah, I think you are mistaken. Like Jacob said a track can be anything. The main thing of Free Rider is that you can draw whatever you want and that you have to use your creativity. A teleporter could give the community another tool to be creative with and do a few of the things I wrote in my previous post. The game is for all types of tracks. Art, fast paced tracks, trials, puzzle like tracks, etc. It's what makes the game fun. You can draw whatever you want and be as creative as you want.

Also I don't get what you mean with super advanced scenery options. All that I wrote in my previous post should be achievable with portals
