I didnt like this game at first but since it had badges and card I just kept playing it. And after a while I really started to like the game. Got all badges and card now. I rate it 4/5.
this badge should be easy or medium. Remember you can set game difficulty to what you want in the options menu. Also you get 5000 points for each day you survive so going to day 15 should be enough for the badge.
YES! Finally got my time down to 3:45. You just have to keep trying. Eventually you will learn how to complete every single level the fastest way possible. Don't waste any time on the mines and the mini-ships level. Just throw yourself and all your allies at them and hope for the best. Might be necessary to get a few growth and ally upgrades this way because you will take alot of damage.
Very fun game but the speed demon badge is just IMPOSSIBLE to get. Ive tried many times with different upgrades. I complete the lvls as fast as possible but theres always some waiting time between each lvl. I dont know how anyone can get this badge...
