Level 1

Spoiler

I think your hidden draggable is jammed. It rattles, but won't release, and there's nothing else to move, unless I'm missing something.

@Don G Rowe Thank you for comment. Maybe you missed something. I tested the level and works perfectly.

Spoiler: Hint

The main draggable block will stuck unless you remove 2 hidden locks.

Spoiler: Hint

Some of draggable blocks can't be seen because it covered by shadow.

@meko Thank you for comment. I'm sorry for accidentally imitating your level because parodying original level maybe a common idea.

I actually got it from Meko's comment. It's really quite similar.

I just tried Meko's level 'Begin Again'. There is one similar thing....

Spoiler

the placement of a lock is same

Spoiler: Where is the lock? 1

hidden in the house

but the placement of the house and the mechanism is different.

Nice level
