Well, if the rising costs are a bug, maybe take everything else i said about incoming cash with a pinch of salt, because the balance will be wildly different. Hit me up when the update is done and i ll give it another try, this will sure look like i will play a different game ;)
I take no issue about the tutorial, i know the game is in early stage of production and it would be unwise of you to spend too much time documenting every little thing when you re likely changing a lot between each version.
