Just my own two sense. This game is fun and it looks great with the added fact that it does not lag and takes very little cpu. My few suggestions would be the screen size. Some of the text overlaps and you can't read all of it. On top of something onlong the lines of weapon drops. Say you get a random chance from each box to drop a random level up. just one and make it low so that when you get it you can feel pretty good about it.
Just a quick note for some items easy. go to gino mountain and go to the top left in the cave the room with 8 chests just kill everythign in it and run out and in oping the chests each time
