I've had a number of fun games, and just won my first game yesterday. I think the combination of Archangel Armor and Ninja Costume is bugged, though. It gets worse (better for me! worse for game balance) every round by adding ever increasing amounts of armor. It must have something to do with haste gain + the free dodge from Ninja armor. In the final boss fight I received more than 2000 armor at the end of my last round. In my game stats I have more than 65,000 armor gained and just over 2000 armor lost in total. If I shield up initially and wait for my natural armor gain to take over, I don't have to worry about anything other than curses. The armor I gain during my attack turn is reasonable (still scales, but as you'd expect), but at the start of the enemy attack round I magically gain tens, then hundreds, then thousands of extra armor as the rounds continue.
