Thanks so much for the detailed feedback, I'll look over it with more attention.
It would be awesome to hear your feedback on the new game mode, I just released today in the game page as HTML5 (the build that plays automatically)
Oooh. I like the contract setup, but a few bugs. After you complete it it doesn't reset and wins the game again immediately. There is also no restart when you've started so I can't get around that tutorial at the start - and you can't lose anymore, even if you turn everything off. you just lose all the contracts. Some of the cancelled contract pop ups don't seem to always clear. The strategy is basically the same as before. I like that the player controls the power requirements with the contracts.
First time i won in 10 days and it was two slow, second time 5 days and it was still too slow. Not sure how quick I gotta beat it to get higher than a one star.
