Thanks for the feedback! I'm not sure why moving around would have been jittery. I'll have to look into that and see if I can replicate it.
Yes, the game is taken by the perspective of someone who doesn't know whats going on. The character doesn't know - they're only a passenger. And you don't know. Lots of games do this to give more of a natural reason to explain some things. It also adds some mystery and interest as you say.
Yes, sorry for the abrupt ending. There's a lot more to the idea and I neglected to figure out an ending for this shorter version. It's a good leason for next time. Even in short game jam games people want/need closure.
Thanks again!
