Like everyone keeps say, great concept, poor follow through. I'm definitely down for a leveling system and for equipment to actually do something, especially with that low drop rate. Maybe an increased level of difficulty as you progress. Also, you could stick a story in there, it's not that hard. Why is my guy fighting these monster? But, you know, that suggestions just for fun. All in all, solid idea, needs some improvement. You add more to it, you could have a great game on your hands.
