Hi, i thought about background noise (wind sound) when you are above the surface, but i had no noise which was different enough from the underwater noise/sound.
With so little time i had no time to add a menu etc. and no even any sprites lol
Yeah the things on the ground should be gold coins but i had no coin sprite^^ and no time to add any upgrades (for example longer air/breath etc.)
thanks for playing and for the feedback
