Woot, not too long to wait then. The demo has a sneak peek at the new third enemy (some orc/pig monster), and there's now more summon upgrades from clearing rooms as well as a life upgrade; nothing new content wise though.
Looks like teasers for tentacle mobs and some type of flying insect type mob as well. Getting full of cum and being quite sticky gives the animation for faster movement. Not sure if that is a bug or not either. Seems like the zombie damage got buffed by (1-2x). Though grappled enemies take less damage for some reason.
And I liked the surprise picture that shows up after you finish the demo. Which also contained even more sneak peeks. 
And if you look on the page (or read this actual thread), it says that it's expected to be out mid October.
Cheat options. Things like increasing the size of enemies, a more powerful dash, bigger explosions etc.
5, you must have missed some. Zombie, Ratdog thingy, Orc, Tentacles, insects. Also the monster act differently when your lust is full. Zombies move faster, ratdog attacks faster, orc does more damage when grabbing, insects will instantly take down enemies with an aphrodisiac, tentacles can grab from other lanes.
You can move the summoned girls to whatever position you like. Just follow the instructions.
