"Dead Estate" is an appropriate name, since my character ended up dying on the first several attempts, lol. It's kind of strange that they are surrounded by ghouls and zombies and what not, run to a mansion, then *split up* instead of acting as a party. But it probably doesn't matter.
It would have been nice to be able to switch between the limited-ammo weapons and the main gun, because I found it a bit tricky to not commit suicide with the grenade launcher in such small rooms that are often filled with pots and/or spikes; it would also be nice to conserve rapid-fire shotgun ammo for that really tough "gym rat monster" that comes around on at least the first two floors. That thing takes forever to kill, with either character. On my second play-through, I tried making it run over spikes in the middle of the room, which seemed to do nothing, for some reason. Then it dropped a heart right on the spikes and I lost a bunch of health trying to get it, lol. Maybe give hearts the same "magnetic" quality as the coins? I like how hearts seem to be more common at lower health levels, though. I couldn't figure out the use for the jump ability, and found myself never using it in combat.
It would also be nice to be able to switch characters when you restart the game, to see if a slightly different strategy works. Not a huge deal though, I copied my review to the clipboard and hit refresh. I think that I died from running into those "blood sperms"--for lack of a better term--the first time around, simply because they were so hard to see/detect. Perhaps that was the point, though.
But constructive criticism aside, this was a sick game. Challenging, but not overly frustrating. Happy Hallowe'en to you all, as well.
