Zoo Fun

It doesn't seem as if there is any point to making the zoo interesting, planning the arrangement, or adding decorations. Do they have an effect? I'd want to see a real effect to them, where, for instance, putting the playground near the petting zoo increases its profits, or putting picnic tables near the burger stand. The restrooms should have a "coverage area" and the profitability of anything not covered should start to suffer. etc. There could also be zoological awards to discover, such as if you make a cluster that includes elephant, zebra, giraffe, and lion, you get a "Natural African Savannah" award and it increases the profitability of all of them. Lead the user to the first of these awards, but let him discover the rest.

To rotate sidewalks, just place the sidewalk down, then click the sidewalk until satisfied with the look. :)

its good work, but it seems more like a pre-release version. There is no challenge, and a few things cold be tightened up. Such as, every shop/cage requires sidewalk access, but the sidewalks don't require access to each other or to the entrance. You can make solitary bits of sidewalk with 4 cages attached, forming a cross shape.

It just seems like a test to verify that the game engine works, which it does, and now it needs to have features and challenges added.

I don't see the point in collecting money. Why don't you just get the money added to your total money?

seems a bit like zoo tycoon, but that just my opinion
