There was an annoying bug in the jungle world. If you have one of the first game releases, it won’t be possible to acces to the level “Jungle boggie”.
We apologize for that error. Now it is solved, and everything will work just fine!
You need to download the game again (from any mirror) and simply reinstall over the old version. You will be able to complete the whole game and you won’t lose your previously saved game.
We apologize again for the troubles, and we hope that you enjoy playing “the creature” game!
