There is a huge reason as to why I don't want you to move/rotate.
For one, if you could move, it would allow access to places you shouldn't be, such as a small hole.
Two, if you move, you would not be aligned with the grid, thus giving you away.
Three, if you could rotate, you would not be aligned with the grid.
Four, it would be buggy, glitchy, and hard to accurately do.
Five, I picked a 2x2x1 brick for simplicity.
New suggested feature: When taking on the chest color, it matches to the closet color in the colorset. If I could figure out how to determine the color, I could report back the best color to use in the provided colorset.
Also, I'm adding a poll.
