Not sure if the mods can fix this or if I need to open a ticket to speedrun staff, but the initial public release of Zineth (v0_235) is August 12th, 2012.

I recently noticed that if you are in upwards velocity state (mech arms down or waving), if you brake in midair, you will counterintuitively gain altitude as you slow down. I haven't had a chance to try it myself in a run, but it could theoretically shave some time off the To The Moon run, since you don't have to get lucky with hitting the lower bridge wall at just the right angle.
