Had a lot of fun and ended up just playing it in one sitting.
I ended up beating Ms Slithers before I even fought the Creator since I just missed the hole to heck and I didn't even feel like I missed something in the cave, maybe there wasn't enough of a hint or it pushed the juice portal too much and I thought that was the end, but I just missed it. On the other hand the fight with Ms Slithers felt really good, not only did it give a good sense of finishing the game, but also the location just felt right since you quickly find that besides a few building it just becomes endless so it makes sense that the only way left to go is up.
I'm worried about the game getting updates, not that more content is bad, but that I could see it ending up really badly if an important part of this game is missed, that it's weird. What I mean is after you get used to all the strang things in the game they may get boring. A quirky combat and movment system might get annoying after it stops being so quirky. I think if this game keeps getting more content it has to occasonally throw a curve ball to keep the game alien to keep the players from getting settled in.
I could be wrong, it just seems like part of what makes the game fun is the quirky things about it, but I don't think those will stay fun if they just stay the same in a game with a lot longer playtime.
