Perhaps make it clearer what a jetpack is (for those wondering, it's what you use the fuel canisters for on the "get ready" screen).
Also, maybe I'm an idiot, but I didn't get that containers were what we used the keys for. I thought containers were the boxes during the stages.
Finding this game really addictive, but the bugginess is killing it for me. Everytime I start to feel as though I'm making progress, the thing freezes up.
Am I missing something or is there no way to completely turn off the sound effects? I don't want to have iTunes fighting with the sound of screeching birds and tornadoes.
Overall, I liked the game a lot. Two small changes would make it even better.
1) Remove the Kongregate link from the upper-right corner - more than once, I was trying to send my mole out after a gem and accidentally clicked the link, opening a new window and leaving me scrambling to close it because my game was still going.
2) Create some sort of skip option for the trophy-selling, boat-buying section. It's cute the first time, but after that, I just want to play the game again, not wait for a 2-minute animation (a 2-minute animation that has sounds I can't turn off, meaning I can't use iTunes or Hulu while it's going on).
Like I said, really fun game, and with a couple of small changes, it could be even better.
