I got to stage 3 and the game just seems to end at the score screen after completing. Bug or intended?
EDIT: Okay I think I found the problem, though dunno if it's on MY end or not. Stage three seems to be the 'end state' of the demo and when it ends you're expected to put in a 3 letter name or so for high score. But controls just seem to die on me when trying to do so.
