A good try but somewhat lacking
I have been very fond of the princess maker series and took some liking of your demo for that reason. Your game seems to be reasonably true to the spirit of the original but it does leave some things to desire:
The job game gets repetitive quite soon. Also I find that even with pretty good relevant skills the chances of fumbling a working day are irritatingly high. Though it'll take a lot of work, consider altering the mini game rules for the different jobs.
Not being able to try out the advanced jobs is a real downer since it already takes a fair deal of effort to qualify during the demo time.
The skills don't seem to do much except qualify for the jobs or work on some random events, the game needs to expand more in different directions.
Given all this I consider the retail price for the full version pretty steep especially since we don't get to know beforehand how much the gameplay is enhanced in the second phase when advanced jobs come into play.
