Yes, it is possible to get the dragon tamer achievement. You don't need a perfect job score for that. And certain pretraining helps you learn dragon training faster. (Combat skills!)
I am beginning to think that the "Tier" is more related to the TYPE of ending, and not an indicator of rank. I've had terrific games with both low and high tiers, and I've also had terrible games with high and low tiers. (Like the game I am playing now, trying to find an altar with low morals/high sin)
TRY #3: 100% Beggary, Church work, then Stable mucker. School for Theology. Result: The Purveyor of Pascifism, Tier 2 (score 55,788) 2 dungeon trips; neither netted a thing. (Got 3 achievements tho)
Nice game, but truly crappy instructions. "Make cycles" should be "Make shapes" or "make closed shapes". Without good instructions, one doesn't realize that there is far more going on in later game levels.
As someone else mentioned, you can make your own custom levels to help with some of the awards. I think that maybe the "All Done" award is bugged: what someone else said about having to have all 90 awards sounds right; I bet the author checked for 90 instead of 89.
Too easy, but I have to mark it down because I can't get the "All Done" award. A marker on your monitor is all you need for Platinum.
Broken speakers: click the music/mute icon fast about 10 times. Visit all the links on the main page. Send in 1 level (you can use a bogus email address). The rest of your awards come as you complete the levels, except maybe for distance. (Just keep trying for long orbits)
Hated it. Terrible key configuration. Graphics of a 2 year old with crayons. Fun factor of 1/5 stars. (Really, what was this, an experiment in programming?)
