Thanks for the kind words! Survival mode ultimately isn't a focus, so I'm not sure if it will be cut or not, but the main game will actually have levels and things to maneuver around and places you can't go. As for pickups, all enemies drop the same pickups, but you only get the kind you need. As in, health won't appear if you are at full health, which leads to more money spawning. So playing well and without using your superweapons means that you get more money to upgrade your stuff with. We'll see how it goes from here, but the focus of next demo day is to have all the base weapons in and try to get a level or two going, which should be more representative of the final game.
