Need Help with two Puzzles

[Enderkatze]

So in the Valley where you get the MacGuffin Gun,there are two Puzzles I'm having a hard Time solving.For one,I can't get into the Room in the Wall on the opposite Side of the Entrance.The one with the Two-Second Timer Button.Also,the House with no Entrance,where I can see through the Roof Tiles.
I'm also having a Hard Time finding the last two Seashells,But I'm sure I can find those.
I really want to solve these Puzzles as I really want to get the most out of the Demo until I can buy the Game.

Just buy the game, it's worth it ;)

The shell guy points into the direction of the next shell, when you talk to him.

The two-second timer door you can get in, by using your cube to hold the door open, that's what the ramp is for

The other room with no entrance likely requires a gadget that you earn later in game.

Figured the Door out already,can't find the last Shell.So I can't access the Closed Room until I buy the Game? dammit.I can't afford that.

Is one of the Shells in the Room with no Entrance?

There is no shell in the room with no entrance. As Jumper said just talk to the guy asking for the shells. He will give you the direction to search in.

I mean,He Points straight to the Walled of Room.I Couldn't find it at the Waterfaucet on the Hill behind it.Couldn't find it before the Secret Room.It's gotta be Somewhere in that Direction though,that's where He Points.Also,from Faucetmountain,I could See a Chest,But I don't know how to Reach it.It's on the Nearby Plateu,but when I Tried to Platform to it from the Stick Next to the Yellow Measurestick Bridge,I kept Slipping off of the Rocks from I thought I was supposed to Parkour Off of to get to the Plateu!
