A new version of the demo is out, 0.1.4, which will hopefully clear up most of the issues I've become aware of. The most pressing are being able to run up the mountain in 3rd person mode and being able to move mid-air while jumping.
I'm working on a short spaceship demo to finish out the month. It should be up tomorrow. The full game is pushed back to next month because I don't want to rush out something shitty. Want to make sure it's the best it can possibly be. Still planning on following the release schedule I had in mind: an alpha of everything up till Santa's castle and then the full version of the game following shortly after
