Fun smol game with some good speed juice goin on! As an audio guy, I'd recommend using sound effects from freesound.org with the CC0 or creative commons 0 attribute. You don't need to credit anybody, basically public domain open source audio you can use for anything so ya don't have to rely on mouth sounds alone :p might add some juicy details to the audio portion to match the visuals :) Would also like to see a distance tracker added, could bring some more goals and dopamine to the game~
