All that i can say about this is that it is a game. A game with lots of problems. This is not an insult. First off all i know you adressed this in the description but there is no real reason to play because of the lack of saves. Also You should be able to select multiple units at once. You should be able to assign units to mines and lumber mills instead of them just being there.
this version of the game is by no means a completed product, there was many things that I had planned to add including everything youvesuggested. Unfortunately however the game is no longer in development and at this time I have no plans on picking up the development of the game again.
