Game is still largely unfinished. Expect plenty of bugs and issues.
Reporting anything would help a lot, rather than just playing and not saying anything.
Game should keep you entertained for a good 2-3 hours I'd say. Maybe a bit more or less.
I'll probably be rebooting once or twice to finish adding the quests for the last dungeon (there is only 3 to add).
Once those are added I'll make a start on adding new classes. But don't expect those to be done for at least a few more days.
After that I'll maybe go back and add a few filler quests and what not to make it seem like the game has more stuff to do.
Then I'll start on more content (at the moment, everything is easy mode. Nothing should be too hard yet, you're still in the noob parts of the game, expect ballcrushing hardness once you reach level 15 and change classes).
