I often found people could get a concept up and running (nine levels is impressive) but that there were boring things still to do like high scores, saved games, control configuration UI, settings, etc. that were a sort of hurdle that many people weren't willing to invest in.

Then again, getting something just up to the point that it is playable, a proof of concept, is when you can really see if a game is fun or not. I have floppy disks full of games that never made it past that point because there was just ... something missing.
