Re: 4. ooh! I never saw the bonus things, because I was focused on the "road" haha. My suggestion would be to have them also appear right when you place something down, since then nothing is moving and it could be a bit clearer?
That's a good idea! -thank you! ^_^ hmmmmm now that I'm thinking about it also might make them glow a bit or something too so they stand out more :D
