yoooo, i completed the demo!! with slightly under less than 20 hours.... and lvl 29 hero
although i did use a cheat/bug...
1) go to the recruit screen, then exit game
2) no matter how u get back in, either thru recruit, item cache, or 25% exp, you will get ONE EXTRA CHARACTER; however, the characters will not be the preset ones as determined by the recruit screen, it will just be a mixture of squires and archers
and so i defeated the games with my hero, one cleric, two knights, and three fighters (who are insanely op once leveled up to five) choosing the 25% exp route
also the music is very epic
