Great idea! love the idea to have to rewind the audio recording. The recording is very well done too! love the voice and audio combined everything fits the total theme perfectly!
but i could not get past the first level, i did record both words and they turned white but in the end i could not submit my answer :( it was not clear at first that i had to go to the end to be able to click on the submit-button in the beginning, but when it got white when i was at the end i tried clicking it but nothing happened. Maybe i did make a mistake but if i did it was not very clear what this mistake was.
Overall I did like it and fits the JAMtheme great! i never would have come up with using audio as the main game mechanic, nice!
