LEGO Island 2 Getting into the cut desert tomb in LEGO Island 2 without mods/cheats

[lol username]

 

Usually if you want to access this area you'd have to mod the game, use cheat engine, artificially lower the framerate with external software and clip through the door, etc. Here's an easier way.
1: Go to the position above the door as shown and pull out your board, if you're in the right spot it'll levitate you over the invisible wall.
2. Pull the camera down with the C key if needed, as walk speed and wall climbing ability are bizarrely tied to the camera angle.
3. Get on top of the tomb as shown, and save your game just to be safe.
4: Walk to the start of the tunnel, *definitely* save your game here.
5. Carefully move around until you manage to land inside the tunnel, which usually happens while sliding. I got lucky here and did it on the second try, but usually it takes more attempts and you often fall into invisible water.

I do something like that on OGEL to get past the invisible walls and collect that crystal on the cliff near the pizzeria. I've always liked the sound of the skateboard  Always takes several times though.

Yeah, you can also collect that crystal by walking directly above it on the path to the Brickster's palace - doesn't matter if a collectible is above or below you to collect it, apparently. At least that one can be collected via glitches though, there's one that just plainly doesn't work. It's got solid collision, and even when you use developer debug stuff to give yourself all 10 crystals, all the crystals except it vanish.  (And yes, it is supposed to be one of the collectibles, it's the seventh or eighth of the ten collectible crystal objects if you look at the game object list in dev mode.)
