sorry to hear that. I guess I might have made it too hard but the arrow is really just the basics. It gets a lot harder later and there's more meta than that though
I got the same problem there. I managed to get past that point, but the difficulty really throws me back...
You should make sure the difficulty is adequate for most of the players. Because if you're the one testing the game, it'll always seem easier to you than it really is.
I hope you can fix this somehow :)
