How about the ability to join 10 chests to make one of higher value? Or 20 even? Maybe a way to gamble with the chests that are unopened?
Also, full-screen mode? I have to squint sometimes to see things on my 24" monitor.
I cannot get the "Kill 5 enemies while standing in water" award to work. I stood in the pond and killed at least 20 monsters to no avail. Also, spreadshot would be nice since your enemies get it. Pretty good game otherwise.
