If I choose to create two ( or more ) Game Field UI's and in each I add as control an accelerometer , only the first World's accelerometer will work . So in order to repro this do the following : - create new game - in the wizard input multiple worlds and also uncheck Single UI for World . - add as control accelerometer in both World UI -> export to Android ( haven't check for iOS ) . When the game starts up the first world controls work ok via accelerometer , but move on to the next one and the character won't move at all.
