You totally should've ended the demo on a silly note! like: They go over a hill and before them lies a massive horde of revenents. They charge towards you, but then Funny Berserker says to them, "Hang on guys, we're not allowed to fight you because the silly developer won't let anything past this line." He then points to a short line drawn in the dirt, "but that's ok, because in the full version of this game, this line doesn't exist and we can continue slaughtering you"
You do realize how many of these game's we've played right? We don't need a tutorial... just let people die and figure it out for themselves!! If they are too stupid to figure it out, they should be escorted from the internet.
SPOILER: There's an alternate way to defeat the hammer level. Rotate the first hammer so that it's on the other side of the ball, then knock it so it's in the middle of the rotating platform. Then rotate that hammer so that it's vertically up, then while it's falling click the platform and the ball will drop into the basket: SPOILER
