Good work, developer. Sadly I've already played Torchlight (1 & 2), so I know how good this style of game can be if done correctly. It is still very good for a one-person project, but it of course can't live up to its inspirations.
When you press tab to look at k/d or score, I think that the score should be straight up points, which are at the end multiplied by your exp x2 or x3 skills. This would create a balance where those people with the exp multiplying skills aren't always the #1 player ( allowing everyone the chance to get first place, for contracts )
 "Forgotten Dungeon - Raise undead"){kind=icon}
 "Upgrade Complete 2"){kind=icon}
 "Contract Wars"){kind=icon}
It is the difference between a free game done by only one person and a game made by a team with some budget involved
