Is the pale blue side part of the opening target?

No. The opening target is cream 4 and cyan 1. The translucent pale blue side is a depth wall until a later target phase exposes it.

Why does the cube become a square or arch?

The gray outer band remains while the colored center is removed. Re-read the target row after each contraction.

Clear the final green/cyan pieces, then let the pale blue structure dissolve in the source's completion animation.

Clear Level 33's icy-sided cube from cream and cyan, follow the colored center as it re-presents, and finish the pale blue end pieces.

If the player asks you to sign in, open the video on YouTube instead.

Clear the exposed cream 4 and cyan 1 groups from the colored center.
After the cube re-presents automatically, use the center view to expose the next colored group; do not tap the translucent ice side.
At the colored center between the gray band and the arch opening, follow the green/red/orange row, then the purple/blue, pink, and yellow groups.
Keep the gray band out of the buffer plan until gray is named; a face visible beside the center is still a depth boundary.
When the final row reaches the lower green/cyan pieces, clear them first and let the pale blue side dissolve in the completion sequence.

Colors in this level:

Cream, Cyan, Green, Red, Orange, Purple, Blue, Pink, Yellow, Gray, Lime, Pale-blue

Using the translucent ice side as a shortcut before it is active.
Tapping gray frame pieces because they are closest to an exposed color.
Continuing to tap the previous face set without waiting for the center's automatic re-presentation.

Start with cream 4 and cyan 1 from the exposed colored center.
Let the cube re-present automatically into the center view instead of tapping the translucent ice side blindly.
Wait for the active gray phase before clearing the outer band or pale blue end.

Board notes 5 details

Layout: The opening board is a dense multicolored cube with a gray outer band and a translucent pale blue side. Cream 4 and cyan 1 are active, and the buffer row is empty.
Goal: Advance through green/red/orange, purple/blue, pink, and yellow before clearing the final green/cyan and pale blue pieces.
Opening: Clear the exposed cream 4 and cyan 1 groups.
Danger Zone: The translucent ice side and gray band define depth but are not automatically active when visible.
Mechanics: The dense cube re-presents automatically into a gray square/arch as its colored center clears, then dissolves through the pale blue side; the source does not introduce a new manual swipe.
