I liked this. Got a combined score of 82 - mostly lost points on the first level when I was figuring out the game and the last level where I fumbled all the rules. Game seems simple to start but once you start adding rules and weapon types it builds up complexity nicely.
The procedural item system works well too. The items don't all look samey but they are not so different that you can't identify them quickly. You've struck a good balance.
