My game is not being saved at all in Chrome. Looks like I'm not the only one, based on the other recent comments. Other games on Kongregate save without issue.
Fun game! I just wish the difficulty in Survival mode ramped up much quicker than it does. It gets boring before it gets difficult. I'm currently at level 84 on my first attempt, and I still have all of my mushrooms. Granted, my character is fully maxed out, but isn't that exactly who Survival mode should be geared towards?
The key to getting the hard badge: completely ignore the coins and other bonuses dropped by enemies. They only give you eggs, not points. By now you should have all upgrades maxed, so eggs will do you no good.
