With optimized store placement below: On day 1 you get 1k bonus, and also from day 22 or 23 onwards. By day 27 or 28, they run out of money before they hit the last 2 or 3 stores!
Tips: when placing building, switch to slow just before u get money, then click it in place, switch to fast and watch %. When you get close to 100%, switch to slow until bldg finishes popping up, then switch back to fast again.
By that, I mean Before I finished game, I saved it near the end. Then I finished game, got the Hard badge. Refreshed page to reload game, and after it finished the intro, I got the Medium badge.
Awesome. Apropos music, interesting puzzles without artifical time limit/move limitations. Fun to watch the intricate ballet of arms, and challenging to attempt to optimize the programs.
Buggy - sometimes the radio text does not clear, making it difficult/impossible to tell what you are trying to tell the plane to do. Don't even bother putting a Pay option in until it's bug free.
I have to rate this a 4/5 because of bugs. I like the game tho, taking the protector series another step forward in complexity. (Not sure I like the hours of grinding to gain skills, although I guess that helps folks who can't figure out maps)
I like this one better than the first Sonny, but this one is buggy as hell - I can't seem to save a game unless I start two quick games back to back and save slot 2. (Otherwise slot 1 disappears) Also, only the first two badges worked, and my achievements screen shows no achievements. (Beat it using the middle type of char, but building him as melee with balanced vitality & strength) rated 2/5 for buggy achievements/saves.
Take a screenshot after level 15, then click the link to the right of the badge "Report missing achievement". (Save screeny as jpg or gif to lower size of the image under 2MB)
The correct knife section is lit for a ridiculously tiny amount of time. The sole redeeming feature of the knife section is that the game doesn't make you restart that level if you miss a knife cut - just that one knife guy.
Doing all the harmony levels again got me up to 37 out of 40 levels (on the web page here) but it still won't give me the last badge. (Game still shows all 40 levels done for Inferno)
