Cool idea for a game, I just think a short tutorial or adding what each action does to the description would be a good idea because what some actions do/how to respond to some obstacles is a bit confusing, for example at first I thought the up/down would raise my shield higher or lower to block rather than jump/duck so it took a bit of trial and error to learn what everything did. Also I'm not sure if there just isn't supposed to be any or if there was some bug stopping it but there was no audio for me.
