Rktcr's list of things to do before release is getting pretty spare. One of the major unfinished bullets was the creation of a few more world levels, three of which I had done already, and three of which I finished up today.
I also decided to stream the creation process, and you can watch the recordings over here. At one point I had four simultaneous viewers (though that might have just been a counting glitch).
From left to right, I added: a zone that uses disruptable platforms in excellent (and tricky) ways; a zone all about platform straddling and momentum; and a zone that is about doing straddle jumps.
For each zone, I played through all possible paths to provide information for the world generator (and establish par times).
The above image shows the 127 paths I managed to finish out of the 144 -- that's (3 starts) x (3 ends) x (8 gravities) x (gem / no gem) -- I attempted. Creating these paths tends to take up the bulk of my level-building time; it can occasionally be frustrating, but mostly is a pretty calming experience.
It also impresses me that I'm still finding new refinements and strategies for getting the vehicle around. I think that there are folks out there who are going to connect with this game and do some amazing things.
