Ya, there is still a lot to do on this one. In this initial version of the game there is actually nothing to explore unless you are playing with friends. The only things in the larger world are the npc (or other player) tycoons and the wing store. But in later versions we will work further on both the starting balance and the larger world.
We are pretty sure the spawning under the turtle is caused by having a slightly lower framerate or connection at the start of the game (that is why we didn't spot it until other players were trying the game on different devices). Hopefully we can come up with a solution, maybe even just having a little loading screen at the start so everything has a chance to pop in before the players is dropped on the turtle.
Also, I know it isn't mentioned anywhere right now, but you can just hit "E" on a tile that is ready to collect it. We will surface things like that farm more visibly when we get back to working on this :)
Thanks so much for playing and commenting! :)
