Ok, I've finished the game with this walkthrough, thanks!
One thing I'll say: the right-most opening in the last level, the one where you fall down on the lever after pushing the 2nd box, is obsturcted by the foreground tree. It got me stumped at the end.
Also on the windows build, the sides of the play area does get cut... I recall seeing a half-star in the second to last level (which also confused me, I didn't saw the star at the beginning, and attempted to move from left to right...)
Other than those, Ii was a neat little game to play! Tying up things felt quite satisfying to do. I'd wish we could use the rope more in the game time - apart from using it as a bridge: Maybe we could grab the end point, drag it, and carry it to another endpoint, while pulling connected things along?
Anyways, cheers!
