Ok so maybe it's just me, but I've noticed something. There's one coin missing in the Forest, the third one in the "wall jump trees" that lead to the bridges... but like, I also found 65 coins in the Toy World.
...so I guess it evens out? Is this intentional?
Edit: Wait, nevermind, can't find the 65th coin again.
Edit 2: so it took me doing the thing I needed to do with the 127 coins I had, and being unable to finish that task, and then enter the Forest level again, for all the coins to reappear, including the missing one. Wonderful.
Edit the III: In hindsight that was a fairly minor issue, I had a good time with the game, good show
