Man.. Our health is really very low already and we have no way to upgrade it even as the damage zombies do on us increases with more powerful zombies, which makes it unfair..
I believe that the problem with loading the save file has something to do with not exiting the game via clicking the "exit game" button in the game options
For the first cave, you have to find and defeat a giant spider for the first shard. To get to him, go through the entrances in this order. From the first room, go up, then right, up, up and then left.
It seems its not possible to max out all your skills in one setting, currently I have 300 agi, 280 int, 280 dex and 280 cha, which is the highest you can get. The trick is to max out Credit Junkie as soon as possible by getting the 50 Int and 15 Int stat bonuses early on in the game.
For the 3 balloons achievement in Elephant Quest, you have to complete the quest when you have exactly 3 balloons, not more than 3 or the game may not give you the achievement.
Look at the highscores for Upgrades Purchased, the highest score even reaches 600+ when the max level for each stat is 6 (that implies that the max number of upgrades purchased is 5*5=25). This shows us these people whose highscore exceed 25 are hacking without a doubt.
ALL ACHIEVEMENTS: You Spin Me Right-do a full circle around a level(recommended for level 1). Toggle Toggle!-Toggle 50 levers.

Fallout-Jump off the map 12 times (I suggest level 2). Rolling in it!-Collect all 40 coins. Ow, Pointy-Die on spikes 12 times(Again i suggest level 2). It's Raining Men!-After you complete level 25 press the black button 100 times.
Whoa the ending rocks.. You blast off in a rocket made of rock with the white star you get in the beginning and another orange star you get later as power sources to power the rocket
