The gems take too long to get-- it took about 8 minutes to get Gem 13. After the creatures are maxed,the money needs to be of more use than just resetting the gems.
Funny that the developer is trying to make money with specialty money scheme, eg diamonds on a standard half- rate flash game.
Good but not great game. The money stuck in the water being one of the flaws.
A problem in the hamster room I bounce on the 10, max you can get in the room at one time, I get a jump score of ten but I don't get the achievement, it stops at 66%. I was able to press the button without the the percentage resetting but it still says my best is 10. It looks like others are having trouble with that room. The rest is entertaining though.
the money disappears too quickly. level 13 is one of those that you can barely get any while avoiding the swarms of helicopters spawning all over the over the place.
there's a "bug" in the cave, when you jump near the center (left of the 10 balloon elephant) you get stuck under the platform-- all I could do was refresh.
