Hint:

Spoiler: How to expand

There's a "key" inside the pyramid that unlocks the whole thing, find it by looking in from the holes

Not sure if my gameplay was the intended...

Spoiler

I used the big draggable to push B

but liked the "opening" & the design... thank you for sharing @AreaRankDragon

Spoiler: Intended way

yes, there are two ways to get to the second floor, one of them is using the key to push B and the other is walking on floor 1, and both are intended

Thanks for playing

Also for anyone that wants to do this type of thing if they get inspired by it: if the level expands out of the build limit, B won't be able to walk on the blocks that have made it out of the limit, u can see that parts of my level were intended to have B walk out of the build limit but then we're reformed since it didn't actually work, you would also have to make a lot of holes if your level has a top cuz of the way shadows work in mekorama as of rn

I liked the opening up.

Okay, I got B up both ways.

I also really like the start of the level. Spectacular revelation. Interesting gameplay. I climbed to the second floor very simply - I clicked on the "out of level" block and B climbed on it.
I think that this level deserves at least one 5. And it will be from me. Thank you
