Just replayed your game. The shadow under the bridge makes it so much clearer as to why I can't cross it. I also like that you added a second bridge next to where you find the slingshot to imply that's what you're supposed to use it for, but I think there might be a bug that causes both bridges to be lowered when you shoot down one of them.
Issues aside, I love this game. Good job.
