Bug with the faction coins. while playing as the angle faction there a few stages where it needs one more coin to rank up the buildings. the 24 and 29 stages require one more coin that stays as a left you keep but still need to have.
Very solid game the 100% reward was also worth earning. if you have already 100% the game hit no for the demo then it will ask if you want to do the code theng so you can get both endings without having to grind the game again.
