Your doing it right sir. If the only complaint your getting is that the game is to short (which it is) then your doing a great job.
What i think your doing with the short games (and i may be wrong) is releasing it in parts for development help, and then when the series is finished, Compiling them into One big K.O.L.M. game, with the specs that people prefer? Maybe released as a downloadable game on Playstation Network?
Just a thought.
Other then that, 5 stars, because this is what I think your doing.
