This is an app for multilingual language learning. Mine will focus on the mother tongue.
I tried it out for a bit and found the audio very repetitive, which could be problematic. Minecraft had such good audio - C14 or C11? It is fantastically immersive, and the popularity of the game and audio is irrefutable if you look at longevity (games come and go often, and very few manage to stick and have a continuous impact, Minecraft is a good example of an exception to this, alongside other well adjusted and designed games.
I had fun learning the clicks in isiXhoso - something I want to practice, but the audio became too much as i hit the image repeatedly.
There's room for more resources. This application does not speak to all children, and no one application ever will, hence the need for many across a broad range of cultures and diversities.
