Ok, I tried to give this game a chance but as the devs are unable to make this game run remotely stable I'm out. Don't invest any time or money into this!!
The real challenge in this level pack is not to get stuck with the cat so you don't have to redo the level... Suggest to add an option to start with the next cat without having to redo the whole level.
Thanks Yamamba, anyway I will provide soon a 100% english game without any issues. This upload was mainly an attempt to see how Kongregate works.
