Amazing game. There are a few issues with the teach(took me 3 or 4 games to understand what I'm doing) and some UI problems (would be nice to get a warning if you're about to lose, it's not clear what the buildings are just by looking at them) - but really that's just nit-picking. Really fun stuff. Music is great too!

They were quite distinct - it was easy to tell them apart, just hard to figure out which is which. "Fan" building was the only obvious one for me. I think if the game just showed name of the building when hovering over it, I would quickly learn about the buildings (I think I just wasn't paying attention to the look of a building immediately after placing it).
