Those million hits and ten million moneys medals sure took a while to get! :/ It was a bit unclear if the medals rewarded only existing cash and hits on a per level basis as well, since the counters seem to be reset between levels. It feels a bit unmotivating that you start each level new, even after spending so much time upgrading on the previous, but there is some comedy to how the zombies get tougher and tougher and you just slave away for ages to bring them down, having to resort to even drones and gundams to deal some damage. Could make for entertaining parody movies too. :)
I liked the game overall, but for some medals the amount of grind required is almost too much. Especially when there's no 'stats' page, or counter to let you keep track of your progress. You don't even know if your progress is saved, between levels, or plays. Some more feedback would've been nice. Good game otherwise.
