Patching skips after a level is released is going to be a poor experience for a lot of people. It is now not possible to beat my time because you added a killgrid randomly. I guess at least this one is visible, but people skipping parts of your map is not a problem that needs fixing

There is an editor channel in which you can ask other players for feedback on your level, so that you don't need to change it after its released (usually someone has played it and gameplay changes can make the level messy).

Now it's already better.

These issues have now been fixed, thanks for the feedback.

There are so many obstacles on the track that gripflying though the whole level is easier than trying to stay on the track. Some VirusShards block the whole track at spots where you would usually try to land and their holo often appears too late to dodge them.
Overall the level is a bit dark. If you increased the ambient lighting a litte, you could see obstacles better.
Invisible KillGrids are just nasty.
