engliche pronunciation does not coincide with British English

I gave this game to my 7 year old daughter and she plays already excited all ages of 1-4. Much is self-explanatory, so even younger elementary school students have a lot of fun with the game.
What bothers me personally is the pronunciation, the more the Oxford English, as the British English primary school conveys. Especially with common Wörten as cat or black that a spoken instead of ä here, resulting in the school to confusion. Ultimately, I hope that there will be no problems with it in the 3rd and 4th class. A nice game - just the pronunciation should revise.
