Is there no sound? That's a bummer.
Selecting the level was weird, I selected it then it took a long time for it to register my click.
The smoke from the train looks a bit odd and unnatural the way it comes out and hangs in the air.
What does "place all pieces" do? It's grayed out.
There's a nice sense of satisfaction when I solve a puzzle.
Sometimes the pieces when pulled away from the whole go 'black' and dead, but sometimes I can place them as their own thing. It's unclear to me when or how I get one or the other.
There's a weird square that appears in the top left when I'm placing pieces.
It's super annoying when I'm building and I reach the end of the play area. Why not make the play area infinite if I get to the edge?
I got filtered on the bow level.
