Uranus

Next up: Uranus

Hopefully Mars's fog didn't mess with you too much because Uranus will be the foggiest planetary track from me.
There are a few similarities akin to Neptune here, but not entirely. The Uranian environment isn't suited for human eyes, so you may see illusionary surfaces. The aliens, however, are no hallucination. Try not to get distracted by them.

Other than that junkz, everything else you'll need to know is in the Readme.

If the Uranian atmosphere is too much for you to handle, you can remove the fog yourself in the .INF file. I know Last_Cuban loves to do that. There are things hidden in the fog, if you haven't figure that out already.

Since there are multiple stars in Practice Mode, you will need to find one and not restart/re-enter the track, otherwise the rest of the stars will disappear. They won't disappear once you've found one and stay in the track.
If you do exit, you'll have to go into the 'profiles' folder where your game is installed and erase the level data file for the track. Doing that will reset your progress of the track and put the stars back.

*One of the Fluttering Fungi can get in your way as an obstacle. Try going around that particular one. It can't see you.*
