Hey.
I saw your TAS WIP on youtube and wanted to let you know I released the full version of the game earlier today.
The full version's release topic is
{here} (external link), in case any one else is interested in helping this TAS out.
Some spoiler-ish things concerning speed-running:
In case you aren't aware: Later on, in the Sand Zone's teleporter puzzle, you can use the Dog Whistle to reset the teleporters. I put in a shortcut wherein resetting the teleporters actually sets Booster's teleporter directly to Misery.
I also made the Critter Juice subquest no longer require talking to Monster X to initiate it, so that should help cut down on some time too, by simply heading straight for Chaba. That said it MIGHT be possible to skip the entire thing with frame-perfect boosting across the death spikes in Labyrinth W, but I'm not entirely sure.
