Gus Learns Croatian for Kids

This is a good and engaging app, but for God's sake what kind of accent is this!? Definitely not the accent spoken in Croatia (sounds like a heavy Bosnian accent to me). What is 'bicikla'? That word doesn't exist in standard Croatian. Please, find some native speakers of Croatian Croatian, not Bosnian Croatian!

love the app but absolutely hate that the sound effects (i.e when you get a word right or wrong) are louder than the person saying the word!!! have to turn the volume up to hear the word but get my eardrums destroyed with the sound effects! please fix as this makes it hard to use in public with earphones and there is no way to turn down the sound effects!!!
