Very Nice!
Good game... a bit repetitive but fun. Not sure how the loot system works but I ended with like, $5000 extra... could use some more items or something I guess.
It ran smooth on high quality for a bit, then around level 7 it started to lag up so I dropped to low qual and by the end of the game I was again starting to notice it slow down. (And I'm on a next gen, sli machine)
The only real problem I had with it was the ending. I know in order to have an end it'd need a plot, but it could e something as cliche as a picture of your knight on top of a massive pile of zombies or something saying you saved the day... or saved your kingdom... or just something other than... "GAME OVER"
"Game Over" feels like you lost... "The End" with some sort of triumphant picture would feel more appropriate.
In any case, I enjoyed it. Keep up the good work.
